Abstract
본 발명은 액정표시소자의 백 라이트장치 및 이것의 제조 방법을 개시한다.개시된 백 라이트장치는 도광판,상기 도광판의 장방향 측단부에 제공되는 형광 램프로부터 방출되어 도광판을 통과하는 빛을 외부로 확산시키기 위해 도광판의 한 표면상에 부착되는 확산판,및 도광판에서 상기 확산판의 대향하는 표면상에 부착되는 반사판을 구비하는 액정표시소자의 백 라이트장치에 있어서,상기의 확산판이 없는 대신에 빛 확산성을 갖는 재료로서 확산 박막이 한 표면상에 형성되어 있는 도광판을 구비하는 것을 특징으로 한다. 따라서,백 라이트 장치의 두께가 크게 감소되었기 때문에 이를 구비하는 액정표시소자의 경박단소형화에 크게 기여한다.The present invention discloses a backlight device of a liquid crystal display device and a method of manufacturing the same. The disclosed backlight device diffuses light from a light guide plate and a fluorescent lamp provided at a long side end portion of the light guide plate to pass through the light guide plate to the outside. A backlight device of a liquid crystal display device having a diffuser plate attached to one surface of a light guide plate to reflect the light guide plate, and a reflector plate attached to an opposite surface of the light guide plate to the light guide plate, wherein the light diffuser is diffused instead of the above diffuser plate. It is characterized by comprising a light guide plate having a diffusion thin film formed on one surface as a material having a property. Therefore, since the thickness of the backlight device is greatly reduced, it contributes greatly to light and small size of the liquid crystal display device having the same.
