ABSTRACT:
The reflected light absorbing plate 23 is divided into plural areas by light absorbing walls 20, and is adapted to satisfy a pre-determined condition among the width of one area d, thickness thereof t and the refraction index of the absorbing plate n. The reflected light absorbing plate 23 is applied to the display panel 134 having a polymer dispersed liquid crystal layer as a light modulating layer 16 via a light coupling layer 14. The reflected light absorbing plate 23 and the light modulating layer 16 are spaced by a pre-determined distance taking MTF into consideration. While the light 17a diffused at a minute area A is reflected at the interface 21 with air, the light is absorbed by the light absorbing wall 20 and never returns to the light modulating layer 16.
