ABSTRACT:
The present invention provides a three-dimensional display comprising an LCD projector, a diffusing plate arranged on a surface on which an image projected by the LCD projector is formed, and a parallax barrier having slits in the shape of vertical stripes which is arranged on the side of a viewer with respect to the diffusing plate, wherein a lenticular lens plate is arranged on the side of the LCD projector with respect to the diffusing plate, and an image having black portions each having a larger rate of the width than that of a black matrix on the LCD projector is formed on the diffusing plate without decreasing brightness by the function of respective lenses constituting the lenticular lens plate, thereby to increase the ratio of each of the slits of the parallax barrier at which there is no crosstalk region.
