<p>A display device has a light guide plate formed with a display pattern by a plurality of diffusion dots having translucency in a display pattern formed region, a light shielding layer, and a light source. A plurality of the light guide plates are arranged facing each other, and the light shielding layer is sandwiched between the light guide plates. Light from the light source is selectively introduced to one of the light guide plates to display the display pattern of the light guide plate. The light shielding layer has a surface facing an observer's side formed by a low reflectivity material and a surface facing a side opposite to the observer's side formed by a high reflectivity material. A region facing the display pattern of the light guide plate positioned on the side opposite to the observer's side than the light shielding layer is cut out.</p> |
