Electro-optical device and electronic apparatus

Abstract

To provide an electro-optical device and an electronic apparatus that can improve light-blocking property with respect to light incident on a semiconductor layer.SOLUTION: An electro-optical device comprises: a substrate; a transistor having a semiconductor layer including a drain region, a source region, and a channel region and extending in a first direction, and a gate electrode; a scanning line; and a first light-blocking portion. The substrate, the semiconductor layer, the gate electrode, and a layer at which the scanning line is provided are arranged side by side in a second direction. The first light-blocking portion includes a first portion, a second portion, and a third portion. The first portion is provided between the substrate and the layer at which the scanning line is provided, the second portion is provided between the semiconductor layer and the layer at which the scanning line is provided, and the third portion is provided between the gate electrode and the layer at which the scanning line is provided. A length of the first portion in the second direction, a length of the second portion in the second direction, and a length of the third portion in the second direction are longer in this order.SELECTED DRAWING: Figure 5
