EDGE-LIT SURFACE LIGHT SOURCE DEVICE |
| 摘要 |
LED light source substrates (140) in an edge-light type surface light source device are disposed with a light guide plate interposed therebetween. A length of each of the LED light source substrates is shorter than a length of a plane of incidence of the light guide plate. The chromaticity of light from a central part (141) is uniform, and the chromaticity of light from ends (142) is more shifted toward blue than the chromaticity of light from the central part (141). |

1. An edge-light type surface light source device comprising:
linear light sources; and a light guide section for emitting surface light when linear light from the linear light sources is incident on the light guide section, the linear light sources being disposed with the light guide section interposed therebetween, each of the linear light sources being shorter in length than a plane of incidence of the light guide section, the linear light sources being configured such that the liner light has nonuniform chromaticity. |
