The display device of claim 1, further comprising a baffle disposed to surround each of the first, second, and third actuators with the first and second partitions to define first, second, and third spaces respectively around first, second, and third actuators. 12. The display device of claim 11, wherein the baffle includes at least one of an adhesive portion and a sealing portion. 13. The display device of claim 1, wherein the support structure includes first, second, and third support holes into which the first, second, and third actuators are respectively inserted such that the first, second, and third actuators are fixed to the support structure. 14. A display device, comprising: a display panel having first, second, and third areas;at least three sound generating actuators including first, second, and third actuators each spaced apart from the other two in a long axis direction of the display panel, wherein the first, second, and third actuators each directly contact the display panel at the first, second, and third areas, respectively, to generate sound by vibrating the display panel;a support structure at a rear side of the display panel configured to support the at least three sound generating actuators; a first partition configured to separate the first and the second areas; and a second partition configured to separate the second and the third areas, wherein at least three sound generating actuators further includes fourth and fifth actuators respectively disposed in the first and third areas,wherein the fourth actuator is below the first actuator, and wherein the fifth actuator is below the third actuator,wherein the first partition includes a first bent portion bent toward the first actuator, a second bent portion bent toward the second actuator, and a third bent portion bent toward the fourth actuator. 15. The display device of claim 14, wherein the first partition is arranged in a zigzag form such that the end position of the first bent portion is directed to the first actuator, the end position of the second bent portion is directed toward the second actuator, and the end position of the third bent portion is directed toward the fourth actuator. 16. The display device of claim 15, wherein the second partition includes a fourth bent portion bent toward the third actuator, a fifth bent portion bent toward the second actuator, and a sixth bent portion bent toward the fifth actuator, and wherein the second partition is arranged in a zigzag form such that the end position of the fourth bent portion is directed to the third actuator, the end position of the fifth bent portion is directed toward the second actuator, and the end position of the sixth bent portion is directed toward the fifth actuator. 17. The display device of claim 14, wherein the at least three sound generating actuators further includes a sixth actuator disposed in the second area.
