摘要： A method for illuminating a liquid crystal display device, a back-light assembly for performing the same and a liquid crystal display device using the same can improve the front luminance and production yield. Lights from a lamp is incident to a LCD panel side, which are then primarily diffused for a uniformity of the luminous flux of the incident lights. The luminous flux of the primarily diffused lights is condensed with respect to a first orientation component on a plane in parallel with the LCD panel, and then partially and secondarily diffused for extending a view angle of pixels of the LCD panel. After the luminous flux of the secondarily diffused lights is condensed with respect to a second orientation component perpendicular to the first orientation on the parallel plane, the condensed lights are illuminated onto the LCD panel. A diffusion sheet for secondarily diffusing the luminous flux and a condensing sheet for condensing the second orientation component are formed by a single sheet to reduce the manufacturing process of the liquid crystal display device. Also, a defect produced from respective sheets is minimized to enhance the yield.

摘要： A light source device for preventing a light guide plate from being discolored due to a light supplied by a lamp is disclosed. At least one masking film that is made of a transition metal oxide is disposed in a pathway of the light that is emitted by the lamp and transmitted to a display unit to display images in order to cut off ultraviolet rays having particular wavelengths capable of discoloring the light guide plate. Accordingly, it is possible to prevent the light guide plate, which is made of polyolefin resin composition to make it lightweight, from discoloring in yellow.
