Abstract
A transparent display device according to the present disclosure includes a first substrate, an internal layer, and a second substrate. The first substrate is capable of transmitting visible light. The internal layer is provided on a main surface of the first substrate, and includes a plurality of light emitting pixels and a plurality of dimming pixels that are arranged at different positions in plan view. Each of the plurality of light emitting pixels is configured to emit light independently, and each of the plurality of dimming pixels is configured to change transmittance thereof with respect to the visible light independently. The second substrate is provided on a side of the internal layer opposite to the first substrate, and is capable of transmitting the visible light.
