Abstract
A display device comprises an optical layer disposed on a display unit and comprising a cholesteric liquid crystal, and a cover glass disposed on the optical layer, wherein the cover glass includes a flat portion and a curved portion disposed outside the flat portion, and the cholesteric liquid crystal overlaps the curved portion. According to the present invention, by forming the optical layer between the display unit and the cover glass, the variation in color of the flat portion and the curved portion of the cover glass according to the viewing angle can be minimized.
