Patent ID: 8749732

Claim:
A liquid crystal display device, comprising: a support main having a rectangular frame shape with a substantially flat bottom surface; a reflection sheet; a light guide plate over the reflection sheet; a light-emitting diode (LED) assembly including a plurality of LEDs arranged along a light-incident surface of the light guide plate and a printed circuit board (PCB) on which the LEDs are mounted; an LED housing partially covering the LED assembly and including a first portion and a second portion, wherein the PCB is attached to the first portion, and the second portion is perpendicular to the first portion; a plurality of optical sheets over the light guide plate; a liquid crystal panel over the plurality of optical sheets; a bottom cover at a rear surface of the reflection sheet and having at least one side wall; and a top cover covering edges of a front surface of the liquid crystal panel and combined with the support main and the bottom cover, wherein an entire top outer surface of the second portion of the LED housing directly contacts the bottom surface of the support main, wherein a reflective layer is formed only on an inner surface of the second portion of the LED housing that faces the LED assembly, wherein one end of the reflective layer is disposed between the light guide plate and the liquid crystal panel, and wherein an air gap exists between reflective layer and the light guide plate.
