1. A display device, comprising:
a display panel curved in one direction and having a front side from which an image is viewed and a back side opposite from the front side; and
a middle frame supporting an edge portion of the back side of the display panel, wherein the middle frame comprises:
a first support having a first side facing the back side of the display panel and having a predetermined curvature; and
a second support having a first side facing the back side of the display panel and extending at a predetermined angle from the first support from corners of the middle frame, wherein the first support has a first center portion and first end portions, the first center portion being spaced apart from the corners by the first end portions, the first end portions being recessed with respect to the first center portion to allow portions of the display panel that correspond to the first end portions to have less curvature than portions of the display panel that correspond to the first center portion.
 
7. A display device comprising:
a display panel curved in one direction; and
a middle frame supporting a lower edge portion of the display panel,
wherein the middle frame comprises:
a first support having a predetermined curvature; and
a second support extending at a predetermined angle from the first support, wherein the first support has a height difference at an end portion, wherein the first support comprises a first center portion and a first end portion extending from the first center portion and having a smaller thickness than the first center portion, wherein the second support comprises a second center portion and a second end portion extending from the second center portion and having a smaller thickness than the second center portion.
 
15. A curved display device, comprising:
an upper frame curved in a direction;
a lower frame curved in the direction and disposed opposite to the upper frame;
an intermediate frame curved in the direction and disposed between the upper and lower frames; and
a display panel curved in the direction, the display panel disposed between the upper and intermediate frame,
wherein the intermediate frame comprises a side wall extending towards the upper and lower frames, and an upper terminal of the side wall is in contact with the upper frame and a lower terminal of the side wall is in contact with the lower frame,
wherein the intermediate frame comprises a ring which has an outer peripheral facing and in contact with an inner side of the side wall and an inner peripheral forming an opening exposing a portion of the display panel, and the ring comprises an upper surface facing the upper frame and a lower surface facing the lower frame, and
wherein the upper surface of the ring of the intermediate frame comprises at least one protrusion protruding towards the upper frame and in contact with the display panel, wherein portions of the upper surface of the ring corresponding to corners of the display panel are recessed in a direction normal to a corresponding portion of the display panel from the protrusion to allow for the display panel to have a greater radius of curvature at portions of the display panel corresponding to the corners than at other portions of the display panel.
