Semiconductor device having insulation layer with concave portion and semiconductor layer that includes channel area disposed at concave portion, electro-optical device, method of manufacturing semiconductor device, method of manufacturing electro-optical device, and electronic apparatus

摘要

A first insulation layer includes a concave portion. A semiconductor layer includes a source area and a drain area, and a channel area disposed at the concave portion of the first insulation layer. A gate insulation layer covers the channel area. A gate electrode is disposed to be opposed to the channel area via the gate insulation layer. A first electrode is one of a source electrode and a drain electrode. A second electrode is the other of the source electrode and the drain electrode.
