본 발명에서는, 관통홀이 구비된 액정표시장치에 있어 관통홀 내 후방 측에 보조LED를 배치함으로써 관통홀 후방에서의 암부 현상을 효과적으로 개선할 수 있다. 더욱이, 관통홀 내에 양측 2개의 영역들에 위치하는 보조LED의 광량이 중앙 영역에 위치하는 보조LED의 광량 보다 작게 할 수 있다. 이에 따라, 양측 영역 근방에서의 휘부 현상을 개선할 수 있게 된다. 따라서, 본 발명의 실시예에 따르면, 액정표시장치의 광분포를 균일하게 하여 화상 품질을 확보할 수 있게 된다.

    The present invention relates to a liquid crystal display device. In the liquid crystal display device provided with a through-hole, an auxiliary LED is disposed on a rear side in the through-hole, thereby effectively improving a dark portion on the rear side of the through-hole. Moreover, light quantity of the auxiliary LED located in two regions of both sides in the through-hole may be made smaller than the light quantity of the auxiliary LED located in the central region. Therefore, luminescent phenomena around the regions of both sides may be improved. The liquid crystal display device comprises: a display panel; a light guiding plate; a plurality of main LEDs; and a plurality of auxiliary LEDs. According to an embodiment of the present invention, light distribution of the liquid crystal display device may be made uniform, thereby ensuring image quality.
