Abstract:
1. An electro-optical substrate, comprising: a transparent substrate; a first light-shielding layer arranged on a first surface of the transparent substrate, in at least part of a region surrounding an opening in plan view, the first light-shielding layer having a thickness of 100 to 1,000 nanometers; a first insulating layer arranged in a position facing the transparent substrate with the first light-shielding layer interposed therebetween, the first insulating layer having a refraction index n and a layer thickness t of less than 285 nanometers, and covering at least part of the first light-shielding layer, the first insulating layer comprising a dense layer and a buffer layer covering the first light-shielding layer; a semiconductor layer, arranged in a position facing the transparent substrate, with the first light-shielding layer interposed therebetween, containing part of a thin film transistor, the thin film transistor including a channel region which is, in plan view, positioned within the first light-shielding layer, a corner edge of the first light-shielding layer and a corner edge of the channel region having a distance L a gate insulating layer covering the channel region; a gate electrode arranged in a region facing the channel region, with the gate insulating layer being interposed therebetween; a second insulating layer arranged to a position covering at least the gate electrode; and a second light-shielding layer provided in a position facing the semiconductor layer with the second insulating layer interposed therebetween, so as to cover at least the channel region, wherein the dense layer is arranged entirely inside a region covered by the second light-shielding layer so that the dense layer avoids the opening in plan view.
