Title: LIQUID CRYSTAL DISPLAY
Abstract:
A liquid crystal display. By arranging a colour light-emitting layer (22), which is mainly made of a quantum dot material, in a liquid crystal display panel (200), the colour gamut performance of the liquid crystal display is improved; at the same time, by arranging a uni-directional light guide thin film (21) at a light-emergent side of the liquid crystal display panel (200), light rays emitted by the colour light-emitting layer (22) can penetrate the uni-directional light guide thin film (21) to propagate outwards; in addition, external light rays are blocked and reflected by the uni-directional light guide thin film (21), and cannot propagate to the colour light-emitting layer (22) so as to excite a quantum dot to emit light, thereby avoiding the problems that a contrast ratio declines, and even a colour cast occurs due to the fact that a traditional quantum dot display is easily excited by external light rays, and improving the display quality of the liquid crystal display.
