Zusammenfassung:	According to the present invention, a liquid crystal display device configures a fastening structure which forms a protrusion piece on an optical film member of a backlight unit of a light guide plate, an optical sheet, and so on, forms an insertion hole in a side wall structure unit composed of a side wall unit of a bottom cover and a second side wall unit of a guide panel as a structure positioned outside the backlight unit, and inserts the protrusion piece into the insertion hole. Furthermore, a light blocking/reflecting film for blocking by covering the insertion hole is provided in the liquid crystal display device. Accordingly, the width of the guide panel is minimized, thereby effectively realizing a narrow bezel of the liquid crystal display device, and reducing a dark space phenomenon and light leakage in an insertion hole part. 본 발명에 따르면, 도광판 및 광학시트 등의 백라이트유닛의 광학필름부재에 돌출편을 형성하고, 백라이트유닛의 외측에 위치하는 구조물로서 보텀커버의 측벽부 및 가이드패널의 제2측벽부로 구성된 측벽 구조부에 삽입홀을 형성하여, 돌출편을 삽입홀에 삽입하는 체결 구조를 구성하게 되며, 더욱이 삽입홀을 덮어 가리는 차광/반사필름을 구비하게 된다. 이에 따라, 가이드패널의 폭은 최소화될 수 있게 되어 액정표시장치의 내로우 베젤을 효과적으로 구현할 수 있고, 삽입홀 부분에서의 암부 현상과 빛샘을 개선할 수 있게 된다.
