Kind Code:
A
Abstract:
PURPOSE: To display high-quality images by lessening color shift and color shading.
CONSTITUTION: Lenses 25b on the exit surface side of a lenticular lens screen 25 project to the exit side of light from black stripes 26. The light rays emitted from the lenses 25b are, therefore, visible without being eclipsed by the black stripes 26 not only in the regions where the angle formed by the normal of the lenticular lens screen 25 and visual line is small but also the regions where this angle is large even when the screen is viewed from diagonal. Then, the color shift and color shading are lessened.
