| 20110164197 | Liquid crystal display device - An object of the present invention is to reduce the exterior of a display device while retaining a display screen at a certain size. A liquid crystal display panel including a TFT substrate formed with a glass substrate and a color filter substrate is stored in a frame made of a metal. In order to avoid the direct contact between the glass substrate and the frame made of a metal, part of an optical sheet included in a backlight disposed behind the liquid crystal display panel is extended to lie between the liquid crystal display panel and the frame, and is regarded as a spacer. Since the thickness of the optical sheet is as small as 0.06 mm, the spacer hardly affects the external dimensions of a display device. Consequently, while a crack of the glass substrate is prevented, the exterior of the display device can be reduced. | 07-07-2011 |
