Abstract
A solar cell construction in a display device is provided. The photovoltaic conversion can be performed with high efficiency by the solar cell construction. The display device includes a front substrate and an opposing rear substrate, which are light-transmissive. The display device further includes an optical control layer, a solar cell layer and an insulating flattened layer. The optical control layer is disposed between the substrates, wherein images formed by the optical control layer are displayed on the outer side of the front substrate. The solar cell layer is disposed in a specific area of the major surface on the rear substrate, between the rear substrate serving as a base for supporting it and the optical control layer, and receives incident light coming from the external surroundings through the rear substrate. The insulating flattened layer is formed on the solar cell layer, wherein the optical control layer is formed on and supported by the insulating flattened layer.
