| description | A color light emitting device comprises a casing, six tubular light sources within the casing, and a reflecting surface. The casing has a bottom surface portion and a side surface portion extending from a peripheral edge of the bottom surface portion. The reflecting surface is provided on each of the bottom surface portion and the side surface portion. The six light sources are arrayed substantially in parallel with the bottom surface in the order of red, green, blue, red, green and blue. The outer-peripheral surface of the red color light source at one end faces the side surface portion. The reflecting surface has a colored portion that is in the proximity of the red color light source at one end. The colored portion is colored to have a blue color which is not a green color disposed near the red color light source at one end, of the green color and blue color. As a result, in the proximity of the red color light source at one end, the amount of red color light decreases and the amount of blue color light increases. For this reason, the luminance balance in the proximity of the side surface portion at one end becomes uniform as at the central part, whereby color unevenness is suppressed. |
