An electro-optical device, comprising:
- a substrate;
- a plurality of pixel electrodes disposed above a plane of the substrate;
- a light-shielding conductive layer disposed above the plane of the substrate, the light-shielding conductive layer having a first portion extending along a first direction, a second portion extending along a second direction that intersects the first direction, and a third portion connected to the first portion and the second portion, the first portion disposed between a first pixel electrode of the plurality of pixel electrodes and a second pixel electrode of the plurality of pixel electrodes adjacent along the second direction to the first pixel electrode when viewed from a direction perpendicular to the plane of the substrate, the second portion disposed between the first pixel electrode and a third pixel electrode of the plurality of pixel electrodes adjacent along the first direction when viewed from the direction perpendicular to the plane of the substrate;
- a first data line extending along the first direction, the first data line overlapping at least a part of the first portion of the light-shielding conductive layer;
- a second data line extending along the first direction;
- a switching element including a gate electrode, a semiconductor layer, and an insulation layer between the gate electrode and the semiconductor layer, the semiconductor layer including a source region electrically connected to the first data line, a channel region overlapping the gate electrode, and a drain region electrically connected to the first pixel electrode;
- and
- a capacitor electrode that forms a storage capacitor together with the source region or the drain region, the capacitor electrode having a fourth portion extending along the first direction and a fifth portion extending along the second direction, the fourth portion overlapping at least a part of the first portion of the light-shielding conductive layer and at least a part of the first data line, the fifth portion overlapping at least a part of the second portion of the light-shielding conductive layer, the fifth portion being disposed between the first data line and the second data line when viewed from the direction perpendicular to the plane of the substrate,
- each of the source region, the channel region, and the drain region overlapping at least a part of the first data line, and
