LIQUID CRYSTAL DISPLAY DEVICE
First Claim
1. A liquid crystal display device comprising:
- a liquid crystal display panel having two parallel substrates and a liquid crystal layer sealed between the substrates;
a light source for generating light beams; and
a dispersion film positioned between the liquid crystal display panel and the light source having a plurality of bar-like structures arranged along a first direction and facing the light source;
wherein the dispersion film is utilized for enabling brightness of the light beams generated from the light source to be increased when a viewing angle is increased, and further utilized for enabling the liquid crystal display device to display an image with uniform brightness.
