Abstract
The present invention provides a curved display device, and relates to the field of display technology. The curved display device comprises a plane display panel and a gradient index lens provided at light exit side of the plane display panel, wherein the gradient index lens makes light exiting from the plane display panel converge toward a center of display surface of the curved display device. In the present invention, by adding a gradient index lens to a traditional plane display panel and using refraction effect of light by the gradient index lens, curved display is achieved without curving the display panel, thus poor display caused by curving the display panel is effectively avoided.
