ABSTRACT:
Display apparatus for a vehicle in which the quality of the display image of the indicator is enhanced and displayed content of the display image can be changed without restraint. The display apparatus for a vehicle consists of a indicator and a prism which are integral with each other. On a third surface of the prism where the prism is held in contact with the indicator is formed a transparent electrode. Along an edge portion of a second surface is printed a spacer and a cover grass is mounted thereon. On an inner surface of the cover glass is formed a dot-matrix-type transparent electrode. Further, between the surface and the cover glass is sealed a nematic liquid crystal to form a twisted nematic cell (TN). On the cover glass is further disposed a polarizing plate, a dispersion plate, and a backlight.
