Abstract
In an electro-optical device, a light shielding layer is provided at a first substrate between a second capacitance electrode and a second interlayer insulating layer, in a layer between the second capacitance electrode of a capacitance element and the pixel electrode. The light shielding layer includes a first portion stacked on the second capacitance electrode, and a second portion that protrudes from an end portion of the first portion, through a side of the first capacitance electrode of the capacitance element, toward both sides in a width direction of a semiconductor layer.
Claims14
An electro-optical device, comprising:
- a substrate body;
- a pixel electrode;
- a transistor including a semiconductor layer in a layer between the substrate body and the pixel electrode;
- a capacitance element including a first capacitance electrode overlapping with the semiconductor layer, the first capacitance electrode being in a layer between the transistor and the pixel electrode, and a second capacitance electrode overlapping with the first capacitance electrode, the second capacitance electrode being in a layer between the first capacitance electrode and the pixel electrode;
- and
- a light shielding layer that includes a first portion overlapping with the second capacitance electrode between the second capacitance electrode and the pixel electrode, and a second portion protruding from an end portion of the first portion, through a side of the first capacitance electrode toward the substrate body side, the first portion being electrically coupled to the second capacitance electrode.
