A liquid crystal display apparatus (liquid crystal display apparatus) has been used widely as a display device that is thin and light, and consumes little electric power. This liquid crystal display apparatus includes a liquid crystal display panel on which a plurality of display pixels are disposed in a matrix, and a backlight unit for irradiating light from the back side of the liquid crystal display panel onto the display pixels. The backlight unit includes a light source such as a cold cathode tube.
A light guide plate is disposed between the light source and the liquid crystal display panel. A light source, a cold cathode tube for example, is disposed in the back side of the light guide plate. Light from the light source is distributed to the light guide plate, and is emitted from the light guide plate to the liquid crystal display panel.
A light source, for example a cold cathode tube is disposed in the back side of the light guide plate. This light source is attached to the light guide plate at a portion disposed at the back side of the light guide plate.
The light guide plate is formed of a resin or a glass material, for example, and has a thickness of several tens to several hundreds of micrometers. For this reason, a light source that is attached to a light guide plate is disposed at a position that is spaced from the back side of the light guide plate. This light source is attached to the light guide plate by, for example, sticking the light source to the light guide plate.
However, because the light source is spaced from the light guide plate, the light guide plate is inclined with respect to the back side of the liquid crystal display panel, and there are variations in the intensity of light emitted from the light guide plate to the liquid crystal display panel.
