Patent ID: 8009247

Claim:
A light source apparatus used in a backlight apparatus, comprising: a plurality of light-emitting diode units each light-emitting diode unit including a plurality of light-emitting diodes of different colors placed closely and nonlinearly on a wiring board, wherein, the plurality of the light-emitting diode units are arranged at predetermined intervals in a predetermined direction on the wiring board, each light-emitting diode unit includes one red light-emitting diode, one blue light-emitting diode, one first green light emitting diode having a first chromaticity and one second green light emitting diode having a second chromaticity which is different than the first chromaticity the first and second diodes are configured such that the average chromaticity of the light emitting diode unit is equal to a predetermined value, the red light-emitting diode and the blue light-emitting diode of each light-emitting unit are provided on a first line that is nearly parallel to the arrangement direction of the light emitting diode units on the wiring board, the first green light-emitting diode and the second green light-emitting diode of each light emitting diode unit are provided on a second line nearly orthogonal to the first line such that respective distances from the first and second green light emitting diodes to the red light-emitting diode and the blue light emitting diode are nearly equal, and the light emitting diode units are arranged such that the first green light-emitting diodes and the second green light-emitting diodes are arranged in a zig-zag pattern along the arrangement direction of the light-emitting diode units on the wiring board.
