Abstract

A liquid crystal apparatus as an electro-optical device includes a TFT including a semiconductor layer and a gate electrode, a scan line electrically connected to the gate electrode and provided in a layer different from a layer where the gate electrode is provided, a capacitance line, and a conductive light shielding film electrically connected to the capacitance line. The light shielding film is provided in a layer between the gate electrode and the scan line, and in a plan view, overlaps with at least a part of a low-concentration drain region of the semiconductor layer.
