LIGHT SOURCE ASSEMBLY, BACKLIGHT MODULE AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

A liquid crystal display includes a liquid crystal panel and a backlight module. The backlight module includes a light guide plate, a light source assembly, and a diffusion member. The diffusion member is disposed between LEDs of the light source assembly and a light incident surface of the light guide plate. The diffusion member includes a first transparent layer adjacent to the LEDs and a second transparent layer adjacent to the light guide plate. A refractive index of the first transparent layer is greater than that of the second transparent layer, and a refractive index of the second transparent layer is greater than that of the light guide plate.
