Abstract:
In the present display apparatus, the directivity of light emitted from a backlight is set high in the direction along which a pixel pitch is long, and such light is caused to spread by a lenticular lens. In this manner, in the present display apparatus, the light entering the lenticular lens is parallelized by increasing the directivity of the light emitted from the backlight. For this reason, an amount of light whose traveling direction can be controlled by the lenticular lens (i.e. light focusing on pixels) can be increased, as compared to a display apparatus in which light emitted from a backlight has a low directivity. With this arrangement, both the frontal brightness and the viewing angle of a liquid crystal panel can be increased.
