Abstract

In a liquid crystal device serving as an electro-optical device, a liquid crystal layer as an electro-optical element is disposed between a base material 10 s as a first substrate and a base material 20 s as a second substrate which are disposed to face each other via a photo-curable type seal material, the substrate 10 s and the substrate 20 s are transmissive and include a plurality of light-shielding patterns disposed at intervals in a seal region of the substrate 10 s where the seal material is disposed, and on the substrate 10 s , a semiconductor layer of a transistor included in a driving circuit for driving the electro-optical element is disposed to overlap, in plan view, with at least one of the plurality of light-shielding patterns.
