摘要:
A pixel electrode is disposed with an inclination angle to a base member on a front side (namely, an opposite substrate side) of a liquid crystal display panel. The relation between the reflecting surface of the pixel electrode and the main surface of the base member on the front side of the liquid crystal display panel is defined so that the difference between the reflecting angle of light that is entered as incident light and reflected on the surface of the base member and the leaving angle of light emitted as display light via the liquid crystal display panel exceeds the collection angle of the display apparatus. Thus, undesired light on the main surface of the base member of the display surface 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, 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 surface of the dichroic prism. Thus, an image with a high quality, and a high contrast ratio can be displayed.
