Abstract:
A reflection type liquid-crystal display apparatus comprising:a reflection type liquid-crystal display panel; at least one illuminator; and an optical path control layer; wherein the liquid-crystal display panel comprises a liquid-crystal cell and a reflection layer, the liquid-crystal cell including a back side cell substrate, a visual side cell substrate, and a layer of liquid crystal, the back side cell substrate including a support substrate and an electrode provided on the support substrate, the visual side cell substrate including a transparent substrate and a transparent electrode provided on the transparent substrate, the transparent substrate in the visual side cell substrate being thicker than the support substrate in the back side cell substrate, the layer of liquid crystal being held between the back side cell substrate and the visual side cell substrate with their respective electrodes disposed opposite to each other, the reflection layer being provided at the back of the liquid-crystal layer in the liquid-crystal cell so that external light incident on an outer surface of the visual side cell substrate is reflected by the reflection layer and so that display light transmitted through the liquid-crystal layer is made to exit from the visual side cell substrate so as to be viewed, the illuminator being disposed on at least one of side surfaces of the visual side cell substrate, the optical path control layer having a thickness of in a range from 10 to 300 &mgr;m and provided with light exit portions on the outer surface side of the visual side cell substrate, the light exit portions including optical path changing slopes by which light incident on the side surface through the illuminator is reflected toward the back side cell substrate, each of the optical path changing slopes being inclined at an inclination angle of from 35 to 48 degrees with respect to a reference plane of the liquid-crystal display panel.
