Liquid Crystal Display

Abstract

A liquid crystal display includes a light guide plate that guides incident light, a first point light source assembly including first point light source elements that provide the light to the light guide plate and a first support substrate having the first point light source elements, the first point light source assembly being disposed at one side of the light guide plate, a second point light source assembly including second point light source elements that provide the light to the light guide plate and a second support substrate having the second point light source elements, the second point light source assembly being disposed at the other side of the light guide plate, a liquid crystal panel assembly disposed on the light guide plate that displays image information, and a lower container that accommodates the light guide plate, first and second point light source assemblies, and liquid crystal panel assembly.
