20080204628 | LIQUID CRYSTAL DISPLAY DEVICE - An object of the present invention is to provide a liquid crystal display device including a back light in which an electrode support member can be reliably arranged on the base side without concern for thermal expansion. There is provided a liquid crystal display device comprising: a liquid crystal display panel; and a back light arranged on the back surface of the present liquid crystal display panel; wherein the back light is composed of a plurality of bar light sources arranged in parallel in a plane opposing the liquid crystal display panel and a base that supports each of the bar light sources through electrode fittings at electrode sections; wherein the electrode fittings are provided on electrode support members extending in a direction in which the bar light sources are arranged in parallel, in units of the electrode fittings that support a mating electrode section of each bar light source; and wherein the electrode support member includes a portion fixed to the base side at least one point and a portion covered by a projecting portion fixed to the base side at another point, along the extending direction of the electrode support member. | 08-28-2008 |
20080204629 | Liquid Crystal Display Device - A subject of the present invention is to provide a liquid crystal display device in which the reliability of electrical connection between electrodes and electrode fittings can be improved even if there are variations in diameter of the bar light sources arranged in the back light. There is provided a liquid crystal display device comprising: a liquid crystal display panel; and a back light arranged on the back surface of the present liquid crystal display panel; wherein the back light is composed of a plurality of bar light sources arranged in parallel in a plane opposing the liquid crystal display panel and a base that supports each of the bar light sources through electrode fittings at electrode sections; wherein the electrode fittings are each provided with a pair of pressing portions which press the circumferential surface of the electrode of the bar light source from opposing sides of the circumferential surface; and wherein each of the pressing portions is arc-shaped such that the pressing portion surface facing the circumferential surface of the electrode of the bar light source has a concave; and is formed such that the pressing portion presses the electrode of the bar light source through projections formed on the concave. | 08-28-2008 |
20080225198 | Liquid crystal display device - A liquid crystal display device of the present invention includes a liquid crystal display panel, and a backlight arranged on a back surface of the liquid crystal display panel. The backlight includes a plurality of rod-shaped light sources, electrode fittings for holding the rod-shaped light sources, and side wall plates covering the electrode fittings. The electrode fittings are connected to a connection portion extending in the parallel-arrangement direction of the rod-shaped light sources. The side wall plate includes a plurality of projecting members arranged in parallel to each other in the extending direction of the connection portion. The connection portion includes positions which are brought into contact with the projecting members and portions which are not brought into contact with the projecting members. By adopting the above-mentioned constitution, the liquid crystal display device can reduce squeals and the like. | 09-18-2008 |
