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.

Electro-optical device and electronic apparatus

In an element substrate of an electro-optical device, a semiconductor layer of a transistor has an L shape bending to overlap with both a scanning line and a data line. A first light shielding layer overlaps with a lower layer side of the semiconductor layer. A first light shielding wall and a second light shielding wall are provided on both sides of a semiconductor layer portion between a channel region and a second source/drain region (drain region) of the semiconductor layer. The first light shielding wall and the second light shielding wall to which a constant potential is applied prevent the semiconductor layer portion from being electrically affected even when the first light shielding wall and the second light shielding wall come close to the semiconductor layer portion.

An element substrate is formed as a lens array substrate on which a plurality of lenses are formed. In a method of manufacturing the lens array substrate, first recess sections are formed on one surface of the substrate, and then a plurality of lens surfaces, which include concave surfaces, are formed at the bottoms of the first recess sections. Subsequently, after a light-transmitting lens layer is formed to fill the inside of the first recess sections, flattening is performed while the lens layer is removed. Here, the surface of the lens layer on a side opposite to the substrate is a planar surface which is contiguous to an outside area that is positioned on the outer side of the first recess sections on the one surface of the substrate.
