Liquid crystal display device for preventing leakage of light at corner thereof

摘要

In a liquid crystal display (LCD) device, the adjacent sides of a bottom cover, a guide panel, and an top cover are separated to form spaces, and the separated spaces are not aligned to thus prevent a leakage of light to corner regions.

主权项

1. A liquid crystal display device comprising:
a liquid crystal panel; a light source substrate disposed at the side of a lower portion of the liquid crystal panel and including a plurality of light sources mounted thereon and emitting light; a light guide plate disposed at the lower portion of the liquid crystal panel and guiding light made incident from the light sources toward the liquid crystal panel; a bottom cover having a bottom surface and first wall surfaces extending upward from the bottom surface, adjacent first wall surfaces defining a first separated space extending an entire distance between an upper edge of the first wall surfaces and the bottom surface; and a guide panel having an upper surface and second wall surfaces extending downward from the upper surface, adjacent second wall surfaces defining a second separated space extending an entire distance between a lower edge of the second wall surfaces and the upper surface, the bottom cover and the guide panel coupling the light guide plate and the light source substrate; and a top cover having a top surface and third wall surfaces extending downward from the top surface, adjacent third wall surfaces defining a third separated space extending an entire distance between a lower edge of the third wall surfaces and the top surface, the top cover surrounding upper edges of the liquid crystal panel and coupled with the bottom cover and the guide panel to couple the liquid crystal panel, the light guide plate and the light source substrate, wherein the first, second, and third separated spaces are not aligned so that the light from the light source cannot pass through the first, second, and third separated spaces in a straight line path, and wherein the first separated space is spaced apart from the corner of the bottom cover to not be at the corner of the bottom cover.
