Abstract
A front surface of the opposite electrode of a liquid crystal display panel is formed in a curved shape. The relation between the reflecting surface of the pixel electrode and the curved surface of the opposite substrate is defined so that a leaving direction of the light that is reflected by the first face of the opposite substrate is different from a leaving direction of light that is emitted from the first face of the opposite substrate after having been reflected by the pixel electrodes through the liquid crystal layer. Thus, undesired light on the front surface of the opposite substrate is separated from light that is displayed. Consequently, an image free of dazzling and deterioration of contrast ratio due to undesired reflected light can be obtained with a high contrast ratio. In a display apparatus containing the reflection type liquid crystal display, an incident surface to a dichroic prism is an inclined surface including a curved surface, not a surface that is perpendicular to the optical axis. Thus, signal light that is reflected on each reflection type liquid crystal display panel and that is displayed can be separated from undesired light that is reflected on the surf…
