Abstract
An electro-optical device includes a pixel electrode, a light shielding, a first insulator, a second insulator provided to be in contact with the first insulator on an opening region, a base member including a concave portion disposed to an outside of the second insulator and overlapped with the second insulator, and a lens member provided on the base member to cover the concave portion, and having the refractive index higher than that of the base member, in which the second insulator functions as a waveguide which reflects incident light at an interface between the second insulator and the first insulator, and propagates the incident light inside the second insulator, and the lens member refracts the incident light incident on the lens member from the second insulator or the incident light incident on the second insulator from the lens member at an interface with the concave portion.
