Abstract
In a display device such as a mark plate of an automobile, a light conducting member is arranged on the rear surface of a display panel held on a case. A pair of light incident portions are formed at the right and left ends, and a pair of light sources are mounted in the light incident portions. A number of stipples are formed in the rear surface having a greater concentration towards the middle from the right and left ends. The rear surface of the light conducting member is bent inwardly so that the member is smaller in thickness towards the middle from the right and left ends, whereby the display device is small in thickness and the display region of the display panel is uniformly illuminated.
