Claims

[Scope of claim for utility model registration] (1) The display pattern of the display device that displays driving information is reflected toward the driver's seat by a reflective member installed at the instrument panel position of the dash board, so that the display pattern can be seen from the driver's seat. In the vehicle display device, the reflective member includes a light guide plate whose back surface is subjected to a light diffusion treatment, and a light source disposed on a side surface of the light guide plate, and the display device displays the display on the surface of the light guide plate. A display device for a vehicle, characterized in that a pattern is reflected toward a driver's seat side, and light from the light source is diffused on a surface subjected to light diffusion treatment via the light guide plate. (2) In a vehicle display device in which the display pattern of a display device that displays driving information is reflected toward the driver's seat side by a reflective member provided at the instrument panel position of the dash board, so that the display pattern can be viewed from the driver's seat. , the reflective member has a light guide plate in which a groove forming a predetermined pattern is formed on the back surface, and a light source disposed on the side surface of the light guide plate, and the display pattern is directed to the driver's seat side on the front surface of the light guide plate. A display device for a vehicle, characterized in that the light from the light source is reflected by the light source, and the light from the light source is diffused in the groove portion through the light guide plate.
