1. A flexible display device, comprising: a housing including a first support and a second support, the first support having a first recess therein and the second support having a second recess therein, the first support and the second support being coupled with each other by a folding device so as to be folded and unfolded;a flexible display panel coupled with the housing; andgear members that are rotatably installed on the first support and the second support, respectively, to be engaged with each other,wherein:the first support has a first side and a second side, the second support has a first side and a second side, and the first side of the first support faces the first side of the second support when the first and second supports are folded,the flexible display panel is on the second side of the first support and the second side of the second support,the folding device includes a plurality of link members for rotatably connecting the first support and the second support to each other, the plurality of link members including link members coupled to sidewalls of the first recess and including link members coupled to sidewalls of the second recess, andthe gear members maintain an unfolding angle of the housing, the gear members including intermeshed first and second gear members, the first gear member having a rotation axis that is installed on the first support and the second gear member having a rotation axis that is installed on the second support such that there is a fixed relationship between the axes of the first and second gear members and the respective supports whether the housing is folded or unfolded, the gear members further including third and fourth gear members, the third gear member being intermeshed with the first gear member and the fourth gear member being intermeshed with the second gear member, the third gear member having a rotation axis that is installed on the first support and the fourth gear member having a rotation axis that is installed on the second support such that there is a fixed relationship between the axes of the third and fourth gear members and the respective supports whether the housing is folded or unfolded. 2. The flexible display device of claim 1, wherein the plurality of link members includes: a first link member having a first end that is rotatably coupled with a sidewall of the first recess, anda second link member having a first end that is rotatably coupled with a sidewall of the second recess and a second end that is rotatably coupled with a second end of the first link member. 3. The flexible display device of claim 1, wherein ends of the first and second supports, at which the folding device is installed, have rounded edge portions. 4. The flexible display device of claim 3, wherein the ends of the first and second supports, which have the rounded edge portions, together form a semicircular shape when the housing is fully folded. 5. The flexible display device of claim 1, wherein: two end portions of the flexible panel are fixed to the first support and the second support, respectively, anda central portion of the flexible panel between the first support and the second support is not fixed. 6. The flexible display device of claim 1, wherein the flexible panel is attached to an external surface of the housing when the housing is folded. 7. The flexible display device of claim 1, further comprising a locking device for locking the housing when the first support and the second support contact each other. 8. The flexible display device of claim 7, wherein the locking device includes a magnet that is installed on any one of the first support and the second support to couple the first support and the second support with each other by using a magnetic force. 9. The flexible display device of claim 7, wherein the locking device includes an elastic hook that is installed on any one of the first support and the second support.
