본 발명은 액정표시장치모듈에 관한 것으로, 특히 백라이트 유닛(Backlight unit)의 커버버툼에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display module, and more particularly, to a cover bottom of a backlight unit.

일반적인 액정표시장치의 화상구현원리는 액정의 광학적 이방성과 분극성질을 이용하는 것으로, 액정은 분자구조가 가늘고 길며 배열에 방향성을 갖는 이방성과 전기장 내에 놓일 경우 그 크기에 따라 분자배열의 방향이 변화되는 분극성질을 띤다. 이에 액정표시장치는 액정층을 사이에 두고 서로 마주보는 면으로 각각 전계생성전극이 형성된 한 쌍의 투명절연기판으로 이루어진 액정패널을 필수적인 구성요소로 하며, 각 전계생성전극 사이의 전기장 변화를 통해서 액정분자의 배열방향을 인위적으로 조절하고 이때 변화되는 빛의 투과율을 이용하여 여러 가지 화상을 표시한다. The image realization principle of a general liquid crystal display device uses the optical anisotropy and polarization property of the liquid crystal. The liquid crystal has a thin and long molecular structure and polarization in which the direction of the molecular array changes according to its size when placed in an electric field and an anisotropy having an orientation in the array. It has a nature. The liquid crystal display is an essential component of a liquid crystal panel composed of a pair of transparent insulating substrates, each having a liquid crystal layer interposed therebetween, and having a field generating electrode formed therebetween. Various images are displayed by artificially adjusting the arrangement direction of the molecules and using the light transmittance which is changed at this time.

상기 액정패널은 자체 발광요소를 갖지 못하는 소자이므로 별도의 광원을 요구하게 된다. 이에 따라, 배면으로는 형광램프를 구비한 백라이트 유닛(Backlight unit)이 마련되어 액정패널 전면을 향해 빛을 조사하고 이를 통해서 비로소 식별 가능한 휘도의 화상이 구현된다. Since the liquid crystal panel does not have a light emitting element, it requires a separate light source. As a result, a backlight unit having a fluorescent lamp is provided on the rear surface to irradiate light toward the front of the liquid crystal panel, thereby realizing an image of identifiable luminance.
