Abstract

To preferably display an image on a liquid crystal display panel at any time irrespective of a circumferential environment, a liquid crystal display panel (LCD) (1) is constructed by a front side polarizing means (11), a front side transparent plate body (12), a liquid crystal display section (13) of a transmitting type, a rear side transparent plate body (14), and a rear side polarizing means (15). A back light means constructed by a fluorescent lamp (2), a reflector (3) and a light guiding plate (4) having a triangular shape is provided on a rear side of the liquid crystal display panel (1). Further, a light diffusing plate (5) such as a prism plate, a diffusing film, etc. is provided between the liquid crystal display panel (1) and a light emitting face of the light guiding plate (4) of the back light means. A circuit substrate (6) for driving the liquid crystal display panel (1) is provided on a rear side of the light guiding plate (4) of the back light means. All these members are accommodated in a box body (7) so that a liquid crystal display apparatus (200) is formed. In this display apparatus, for example, a semitransmitting reflecting means (10) is provided on a rear side of the rear side polarizing means (15) in the liquid crystal display panel (1).

Claims
