Liquid crystal display device having a light guiding plate with a novel structure
First Claim
1. A liquid crystal display device, comprising:
- a back light assembly including a light source and a light guiding plate positioned at a side of the light source, the light guiding plate including a light incident surface for receiving a light from the light source, a side surface positioned opposite to the light incident surface, a light output surface for outputting the light, and a rear surface positioned opposite to the light output surface, the rear surface being formed with a light diffusing portion for uniformly outputting the light generated from the light source towards the light output surface, the light guiding plate being formed at an inner portion thereof with a light dispersing member for dispersing the light inputted into the light guiding plate;
a display unit for displaying an image; and
a container module for receiving the back light assembly and the display unit.

Abstract
A liquid crystal display device has a light guiding plate with a novel structure. The liquid crystal display device has a back light assembly including a light source and the light guiding plate, a display unit for displaying an image and a case for fixedly receiving the back light assembly and the display unit. The light guiding plate is formed at a bottom portion thereof with a light diffusing pattern for uniformly outputting the incident light. A light dispersing member for dispersing the light in the light guiding plate is provided in the light guiding plate. The leaking light is outputted towards the display unit by contacting with the dispersing particles of the light dispersing member, so the light efficiency and the brightness are improved.
