1. A display device comprising: a first substrate including a display area and a non-display area which is arranged outside the display area;a first dam which is disposed in the non-display area of the first substrate and which includes a first stopper having a recessed groove at a surface thereof;a
1. A display device comprising: a first substrate including a display area and a non-display area which is arranged outside the display area;a first dam which is disposed in the non-display area of the first substrate and which includes a first stopper having a recessed groove at a surface thereof;a first alignment layer which covers the display area of the first substrate, the first alignment layer defining a first portion thereof which extends to the non-display area and terminates in the recessed groove of the first stopper; anda column spacer disposed on the first substrate and inside the first dam, the column spacer having a hydrophilic surface,wherein the first alignment layer covers the hydrophilic surface of the column spacer. 2. The display device of claim 1, wherein a material of the first stopper is different from a material of the first alignment layer. 3. The display device of claim 1, wherein in a top plan view of the first substrate, the first stopper extends in extension directions thereof to enclose the display area of the first substrate and form a closed curve. 4. The display device of claim 3, wherein in the top plan view of the first substrate, edges of the first stopper are uneven along a single extension direction among the extension directions thereof. 5. The display device of claim 1, wherein a minimum thickness of the first stopper is equal to or less than a thickness of the first alignment layer in the display area of the first substrate. 6. The display device of claim 1, wherein the first portion of the first alignment layer contacts the surface of the first stopper in the recessed groove thereof, the first portion of the first alignment layer contacting the surface in the recessed groove of the first stopper defining a thickness greater than a thickness of the first alignment layer in the display area of the first substrate. 7. The display device of claim 1, further comprising a black column spacer interposed between the first substrate and the first dam, wherein the black column spacer includes: a light blocking portion disposed overlapped with the first dam, anda spacer portion disposed on the light blocking portion and not overlapped with the first dam. 8. The display device of claim 1, wherein the first dam further includes a second stopper which is arranged outside the first stopper and spaced apart from the first stopper, the second stopper having a recessed groove at a surface thereof, andthe first alignment layer further defines a second portion thereof which extends to the non-display area and terminates at the surface of the second stopper. 9. The display device of claim 1, further comprising: a second substrate which includes a display area corresponding to the display area of the first substrate and a non-display area corresponding to the non-display area of the first substrate, the second substrate facing the first substrate with the first alignment layer interposed therebetween;a second dam which is disposed in the non-display area of the second substrate and which includes a third stopper having a recessed groove at a surface thereof; anda second alignment layer which covers the display area of the second substrate,wherein with the first alignment layer defining the first portion thereof which terminates in the recessed groove of the first stopper, the second alignment layer defines a first portion thereof which extends to the non-display area and terminates at the surface of the third stopper. 10. The display device of claim 9, wherein a material of the third stopper is different from a material of the second alignment layer. 11. The display device of claim 9, wherein in a top plan view of the second substrate, the third stopper extends in extension directions thereof to enclose the display area of the second substrate and form a closed curve. 12. The display device of claim 11, wherein in the top plan view of the second substrate, edges of the third stopper are uneven along a single extension direction among the extension directions thereof. 13. The display device of claim 9, wherein a minimum thickness of the third stopper is equal to or less than a thickness of the second alignment layer in the display area of the second substrate. 14. The display device of claim 9, wherein the first portion of the second alignment layer contacts the surface of the third stopper in the recessed groove thereof, the first portion of the second alignment contacting the surface in the recessed groove of the third stopper defining a thickness greater than a thickness of the second alignment layer in the display area of the second substrate. 15. The display device of claim 9, wherein the second dam further includes a fourth stopper which is arranged outside the third stopper and spaced apart from the third stopper, the fourth stopper having a recessed groove at a surface thereof, andwith the second alignment layer defining the first portion thereof which terminates in the recessed groove of the third stopper, the second alignment layer further defines a second portion thereof which extends to the non-display area and terminates at the surface of the fourth stopper. 16. The display device of claim 9, wherein a distance between a surface of the first stopper adjacent to the first substrate and a highest point of the first alignment layer from the first substrate is smaller than half a distance between the surface of the first stopper adjacent to the first substrate and a surface of the third stopper adjacent to the second substrate.
