ABSTRACT:
An object of the present invention is to provide a display device for a vehicle which assures that visual recognizability can be improved by using a circular disc-shaped pointer while the pointer and characters, calibrations or the like on a dial overlap each other. A circular disc-shaped pointer composed of a polarized plate and including a slit-shaped indicating portion radially extending from the central part and the outer peripheral part of the pointer is arranged in front of a dial composed of a polarizing plate and having characters, calibrations or the like placed thereon. In addition, a light source is arranged behind the dial so as to illuminate the pointer with the light beam emitted therefrom. A movement is disposed at the central part of the light source to turn the pointer. The polarizing direction of the dial and the polarizing direction of the pointer are determined such that the light beam emitted from the light source permeates through the limited region where the characters, calibrations or the like on the dial overlap the indicating portion 1a of the pointer.
