Abstract

본 발명은 액정 디스플레이용 백라이트 장치에 관한 것으로서, 빛을 내는 광원, 광원의 한 쪽에 설치되어 광원으로부터 나온 빛을 유도하는 도광판, 도광판의 위에 도광판과 평행하게 설치되어 도광판으로부터 빛을 받아 외부로 확산하는 확산관, 그리고 광원으로부터 도광판에까지 끊김없이 에워싸고 있는 은으로 코팅된 일체형 반사막을 포함하고 있어서 디스플레이용 백라이트 장치에 설치할 때 흑연 테이프로 부착할 필요가 없어 공정이 단순화 되어 비용이 절감되며, 설치하며 빛이 광원에서 도광판, 도광판에서 확산판으로 전달되는 과정에서 외부로 방출될 수 있는 틈이 생기지 않아서 빛의 이용 효율이 높아지는 일체형 반사막을 포함하는 액정 디스플레이용 백라이트 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backlight device for a liquid crystal display, comprising: a light source that emits light, a light guide plate installed on one side of the light source to guide light from the light source, and installed on the light guide plate in parallel with the light guide plate to receive light from the light guide plate and diffuse it to the outside It includes a diffuser tube and an integral reflective film coated with silver that is seamlessly enclosed from the light source to the light guide plate, which eliminates the need to attach it with graphite tape when installing it on a display backlight device, which simplifies the process and reduces costs. The present invention relates to a backlight device for a liquid crystal display including an integrated reflective film which does not have a gap that can be emitted to the outside in the process of being transferred from the light source to the light guide plate or the light guide plate to the outside.
