Abstract

In an electro-optical device, a first opening and a second opening are provided in an interlayer insulating layer provided in a layer between a transistor and a scanning line, with a semiconductor layer interposed between the first opening and the second opening in plan view. A portion of a gate electrode is provided inside the first opening, and the gate electrode is electrically connected to the scanning line via the first opening. The second opening does not overlap with the gate electrode, and a portion of a first capacitance electrode of a capacitance element is provided in the second opening, the first capacitance electrode having light shielding properties. Therefore, the width of the scanning line can be made narrower than in a case in which the gate electrode and the scanning line are electrically connected to each other via both the first opening and the second opening.
