| 摘要 |
The present invention provides a transmission type display apparatus ( 4 ) capable of maintaining uniform and high luminance with a smaller number of light sources ( 21, 22 , . . . ). The transmission type display apparatus ( 4 ) of the present invention comprises a transmission type liquid crystal display panel ( 5 ) and a surface emission light source device ( 1 ) that illuminates the transmission type liquid crystal display panel ( 5 ) with illuminating light (F 1 ) from behind thereof, wherein the surface emission light source device emits collimated light (F 1 ) toward the front side in the normal direction (a) over the entire surface, and a light diffusing part ( 7 ) is disposed on the front side of the transmission type liquid crystal display panel ( 5 ) for transmitting incident light (F 2 ), that enters on the back surface thereof, while diffusing the light (F 2 ) isotropically. |
