US Patent 7417628 Liquid crystal display apparatus

A liquid crystal display apparatus comprises a liquid crystal display panel including a display region, a planar light source device having a light exit surface which faces the liquid crystal display panel and from which planar light exits toward the liquid crystal display panel, and a back surface located opposite to the light exit surface, a coordinates position detecting device which detects coordinates of a position designated on the display region; and a frame which has a projection and supports the liquid crystal display panel and the planar light source, the projection being formed integrally with the frame and extending along the back surface with a distance corresponding to a thickness of the coordinates position detecting device from the planar light source device. The coordinates position detecting device is interposed between the projection and the planar light source device and supported by the projection.
