Abstract

A liquid crystal display device (20). The liquid crystal display device (20) comprises a blue backlight source (21), a lower polarizing plate (22), an array substrate (23), a liquid crystal layer (24), an upper substrate (25), an upper polarizing plate (26), and a quantum-excited color-film layer (27). The liquid crystal display device (20) can emit colorful natural light by arranging the blue backlight source (21) that has blue plane light in three lengths, so that the light-emitting efficiency of the liquid crystal display device (20) is improved and the display visual angle of the liquid crystal display device (20) is increased.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display device. Background technique [0002] Liquid crystal display technology has developed into the mainstream display technology, figure 1 It is a structural schematic diagram of a liquid crystal display device in the prior art, figure 2 It is a schematic diagram of a pixel structure of a liquid crystal display device in the prior art. 11 is a white backlight source, 12 is a lower polarizing plate, 13 is an array substrate, 14 is a liquid crystal layer, 15 is a color filter substrate, and 16 is an upper polarizing plate. When the liquid crystal display device is in use, the liquid crystal molecules in the liquid crystal layer 14 do not emit light, and the liquid crystal display device realizes the display function by transmitting the light emitted from the white backlight 11 through the liquid crystal molecules, so the luminous efficiency is low. At ...
