Abstract
A display device includes a dial, a substrate, a plurality of light source parts, and a transmittance adjustment part. The transmittance adjustment part has a low transmittance part in which a transmittance of light is lower than a predetermined value and a high transmittance part in which a transmittance of light is higher than that of the low transmittance part, and adjusts a transmittance of light from the plurality of light source parts. Each of the light source parts includes a first light source and a second light source having different light-emission colors to be alternately switched on lighting. The low transmittance part is arranged within an area corresponding to the plurality of light source parts. The high transmittance part is located based on a midpoint position where the distance from the adjacent light source parts is equal in the circumferential direction between the light source parts.
