Abstract
There is provided a light source, which can efficiently be housed even if the area of the substrate increases while giving extra consideration to the heat radiation of the light emitting diodes in a liquid crystal display device using the light emitting diodes as a light source. A plate-like light source section is formed by arranging the light emitting diodes on a metal substrate. The plate-like light source section is formed to have a larger area than an entrance surface of a light guide plate, and is disposed so as to face the entrance surface of the light guide plate. The light guide plate and the plate-like light source section are housed in a housing case, and the housing case is formed to have a larger depth in a part for housing the plate-like light source section than in a part for housing the light guide plate. A cushion member is provided between the light guide plate and the housing case to prevent the light guide plate from being moved by vibrations.
