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.
