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 backlight assembly includes a light source, a light-guiding plate and a diffusion sheet that includes a first bead layer on a lower surface of the diffusion sheet facing the light-guiding plate, and a second bead layer on an upper surface of the diffusion sheet. To improve image display quality, the hardness of the beads of the first bead layer facing the light guide plate are equal to or less than that of the light guide plate to prevent scratching of the light guide plate.

摘要： In a backlight assembly and a liquid crystal display apparatus having the same, the backlight assembly includes a light emitting diode that emits light and a light guide plate that supplies the light to a liquid crystal display panel. The light guide plate includes a guide recess formed at a first end thereof so as to guide the light emitted from the light emitting diode to a second end opposite the first end of the light guide plate. Thus, the light guide plate may prevent leakage of the light therefrom, thereby improving display quality of the liquid crystal display apparatus.
