Abstract:
The liquid crystal display apparatus includes a liquid crystal panel and the back light device for emitting the light from a light source to the liquid crystal panel through a lens. The light source includes a first LED for emitting the light of a first color, a second LED for emitting the light of a second color, a third LED for emitting the light of a third color, a fourth LED for emitting the light of the third color, a fifth LED for emitting the light of the second color, and a sixth LED for emitting the light of the first color. The first, second, third, fourth, fifth and sixth LEDs are arranged on the wiring board in such a manner as to offset the deviation of the light distribution.
