    • 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.
    • 在本显示装置中,从背光发出的光的方向性在像素间距长的方向上被设定为高,并且这种光被双凸透镜扩展。 以这种方式,在本显示装置中,通过增加从背光发出的光的方向性,进入双凸透镜的光平行化。 因此,与从背光发出的光的方向性低的显示装置相比,能够增加由双凸透镜(即,聚焦在像素上的光)可以控制行进方向的光量。 由此,可以提高液晶面板的正面亮度和视野角。
