Abstract
A first substrate includes a base material having transmissivity, a light-shielding body having a grid pattern in a plan view seen from a thickness direction of the base material, a pixel electrode, a first insulator having transmissivity that overlaps the light-shielding body in the plan view and is disposed between the base material and the pixel electrode, and a second insulator having transmissivity that overlaps the pixel electrode in the plan view and is disposed in contact with the first insulator between the base material and the pixel electrode. The second insulator has a refractive index greater than a refractive index of the first insulator. An interface between the second insulator and the first insulator has an inclined portion inclined away from a central axis along a thickness direction of the second insulator from the incident side of light toward an emitting side.
