Abstract
A color deviation balance thin film, a side-type backlight module and a liquid crystal display device. The color deviation balance thin film is applied to the side-type backlight module and the thickness of the color deviation balance thin film is gradually reduced along the backlight irradiation direction. The color deviation balance thin film is arranged in the side-type backlight module and the side-type backlight module with the color deviation balance thin film is arranged in the liquid crystal display device. When the side-type backlight module with the color deviation balance thin film is applied to the liquid crystal display device, the intensity difference of light at different positions along the backlight irradiation direction can be reduced, and the problem of the color deviation generated in the display picture can be effectively improved.
