| description | PURPOSE: A light guide plate, a liquid crystal display device using the same, and a method for displaying images thereof are provided to prevent moire and realize the uniform brightness of the liquid crystal display device. CONSTITUTION: A light guide main body(210) includes a plurality of sides(212,214,216,218), an upper side, and a lower side to form a solid body. Optical reflective patterns(220) are formed on the upper side of the light guide main body to have angles not in parallel with a first boundary line(213), so that part of the light incident to a first side(212) proceeds to the lower side. A light reproducing element(230) is formed at a second side(214) emitting the light not proceeding to the lower side, so that the light reproducing element reproduces the light to proceed to the lower side.
도광판, 이를 이용한 프론트 조명 방식 액정표시장치 및 이의 화상 표시 방법이 개시되어 있다. 광학 분포를 변경 및 모아레 현상을 방지하기에 적합하도록 도광판의 광 반사면에 형성된 광 반사 패턴에 의하여 유효 디스플레이 영역이 밝은 영역, 경계 영역, 어두운 영역으로 분할되지 않도록 도광판의 측면으로 누설되는 광을 차단한다. 이로써 광학 분포 변경 가능 및 모아레 현상 억제와 함께 보다 향상된 휘도 균일성으로 디스플레이를 수행할 수 있는 장점을 갖는다. |
