ABSTRACT:
A display device includes a translucent member having a scale part, a light source disposed at a rear side of the translucent member and a dial plate. The dial plate has a shield part that is located to shield a first portion of the scale part from a visual side so as to be invisible from the visual side when the light source is off. The scale part has a second portion that is a residual portion of the first portion, and the second portion is visible from the visual side when the light source is off. The shield part has a translucency so that the first portion of the scale part is visible through the shield part when the light source is on.
