Zusammenfassung:	PURPOSE: A back light assembly and an LCD(Liquid Crystal Display) having the back light assembly are provided to improve the luminance of the LCD. CONSTITUTION: A back light assembly includes a light generator(304) for generating light, a light controller for controlling the light generated by the light generator, and a coating film(300). The coating film is formed on the top surface of the light controller and reduces reflectivity of light from the light controller. The light controller is a light guide plate(302) for controlling the path of the light generated by the light generator or a diffusion plate for controlling the luminance of the light. An LCD includes a liquid crystal panel and the back light assembly. The liquid crystal panel includes upper and lower substrates combined with each other, and a liquid crystal layer. 휘도를 향상시키기 위한 백라이트 어셈블리 및 이를 갖는 액정 표시 장치가 개시된다. 백라이트 어셈블리는 램프에 의해 발생된 광의 경로 또는 휘도를 조절하는 도광판 또는 확산판의 상면에 형성되어 광의 반사율을 낮추기 위한 코팅막을 포함한다. 코팅막은 고굴절률의 제1 코팅막 및 저굴절률의 제2 코팅막이 교대로 복수층 적층되어 형성된다. 따라서, 도광판 또는 확산판 상면에 형성된 코팅막에 의해 램프에 의해 발생된 광의 반사율을 낮추고, 투과율을 높임에 따라 휘도를 향상시킬 수 있다.
