20090066904 | LIQUID CRYSTAL DISPLAY PANEL - The present invention discloses a liquid crystal display panel, including an array substrate; a color filter substrate; and primary post spacers and secondary post spacers disposed between the array substrate and the color filter substrate, wherein the color filter substrate is divided into a side portion and a central portion inside the side portion, and the density of the secondary post spacers in the central portion is less than that in the side portion. | 03-12-2009 |
20090256998 | BACKLIGHT MODULE AND LIQUID CRYSTAL DISPLAY - A backlight module and a liquid crystal display are provided. The liquid crystal display comprises a liquid crystal panel, a light source provided below the liquid crystal panel and at least one support member provided on the upper surface of the light source for supporting a liquid crystal panel. According to the embodiment of the present invention, when the liquid crystal panel is subject to a force upon pressing or impact, the force can be counteracted by the support member. Therefore, the deformation of the liquid crystal panel can be effectively reduced so that light leakage can be prevented. | 10-15-2009 |
