A semiconductor device includes: a resin substrate; a display element configured to generate an image; and a circuit layer including a thin film transistor configured to control the display element. The resin substrate has a main body made of resin and a surface layer made of the resin laminated on the main body. The surface layer has a lower electrification property than the main body or the surface layer has a lower film density than the main body. Each of the display element and the circuit layer is on the surface layer.
