The present invention relates to a liquid crystal display device for preventing the deformation of a light guide plate due to heat generated in an LED. The liquid crystal display device includes: a liquid crystal display panel for implementing an image; a backlight unit including a plurality of LEDs for emitting light and the light guide plate for guiding the light emitted from the LED to the liquid crystal panel to face the LED; a guide panel for supporting the liquid crystal panel; a lower cover and an upper cover coupled to the guide panel to assemble the liquid crystal panel and the backlight; and a light guide member which is disposed between the LED and the light guide plate, prevents the heat generated in the LED by coming into contact with the LED, the light guide plate, the guide panel, and the lower cover, and guides the light emitted from the LED to the light guide plate. 본 발명은 LED에서 발생하는 열에 의해 도광판이 변형하는 것을 방지하기 위한 액정표시소자에 관한 것으로, 화상을 구현하는 액정패널; 광을 발광하는 복수의 LED와, 상기 LED와 대향하여 LED로부터 발광된 광을 액정패널로 인도하는 도광판을 포함하는 백라이트부; 상기 액정패널을 지지하는 가이드패널; 상기 가이드패널과 체결되어 액정패널과 백라이트를 조립하는 하부커버 및 상부커버; 및 상기 LED와 도광판 사이에 배치되어, LED, 도광판, 가이드패널, 하부커버와 접촉하여 LED로부터 발생하는 열을 차단하고 LED로부터 발광하는 광을 도광판으로 인도하는 도광부재로 구성된다.
