Description

technical field

[0001] The invention relates to a diffusion sheet, a backlight module and a liquid crystal display device. Background technique

[0002] A liquid crystal display device generally includes a liquid crystal display panel and a backlight module for providing planar light to the liquid crystal display panel. Among them, the diffusion sheet is an important component in the backlight module, which is used to uniformly diffuse and emit the light beam emitted from the light source, so as to achieve the purpose of uniform brightness of the liquid crystal display device.

[0003] see figure 1 and figure 2 , figure 1 It is a three-dimensional exploded view of a prior art liquid crystal display device, figure 2 yes figure 1 Schematic side view of the diffuser shown. The liquid crystal display device 1 includes a liquid crystal display panel 11 and a backlight module 12 arranged adjacently. Wherein, the backlight module 12 provides planar light for the liquid cry...
