Liquid crystal display device using different handedness cholesteric liquid crystals
A liquid crystal display device, which comprises: a backlight source (1); a first handedness cholesteric liquid crystal film layer (2), located at an upper side of the backlight source (1) as a light emitting surface; an array substrate (3), located at an upper side of the first handedness cholesteric liquid crystal film layer (2); a color filter substrate (5), located at an upper side of the array substrate (3); and a second handedness cholesteric liquid crystal layer (4), sandwiched between the array substrate (3) and the color filter substrate (5), the first handedness being opposite to the second handedness. The liquid crystal display device greatly improves light efficiency and transmittance of the display and saves the processing steps and manufacturing costs.
