Abstract: A liquid crystal panel device comprises a liquid crystal panel having a relatively large area particularly while in use with an automobile dashboard and having a plurality of display sections, a diffusion plate disposed opposing the rear face of the liquid crystal panel for diffusing receiving light rays, a printed circuit board disposed opposing the rear face of the diffusion plate, and a plurality of light emitting members disposed in equally spaced relation to each other on the printed circuit board over the whole region of the liquid crystal panel. A reflection plate is provided between the diffusion plate and the board, and a partition plate corresponding to the display section of the liquid crystal panel is provided. Within a space defined by the diffusion plate, board, reflection plate, and partition plate, the light emitting members consisting of three or four incandescent lamps are disposed.
