Abstract:
1. A liquid crystal display device comprising: a liquid crystal panel; and a back light which is mounted on a back surface of the liquid crystal panel, wherein the backlight is constituted of a light guide plate, two linear light sources which are formed of a first linear light source and a second linear light source which are arranged in parallel along at least one side periphery of the light guide plate so that the second linear light source is arranged between the first linear light source and the at least one side periphery of the light guide plate, the first and second linear light sources having different lengths, and a lamp reflection plate which surrounds a side of the two linear light sources opposite to the light guide plate and reflects light irradiated from the linear light sources in the direction toward the light guide plate, both ends of each one of the first linear light source and the second linear light source include a one-side electrode and an another-side electrode, the one-side electrode of the first linear light source which is positioned opposite to the second linear light source with respect to the light guide plate is retracted to another-end electrode side than the one-side electrode of the neighboring second linear light source in accordance with the different lengths of the first and second linear light sources by an amount which allows the connection of a power supply cable to at least the one-side electrode of the second linear light source, a flat cable which is pulled around a surface of the lamp reflection plate parallel to a main surface of the light guide plate is connected to the another-side electrode of the second linear light source, and power supply cables are connected to the respective one-side electrodes of the first linear light source and the second linear light source and the another-side electrode of the first linear light source.
