1. An electro-optical device, comprising:
a substrate;
a colored layer;
a first light-emitting element and a second light-emitting element disposed between the substrate and the colored layer in a thickness direction of the substrate;
a wall portion disposed between the first light-emitting element and the second light-emitting element and the colored layer in the thickness direction and between the first light-emitting element and the second light-emitting element in plan view; and
a sealing layer disposed between the first light-emitting element and the second light-emitting element and the colored layer in the thickness direction, wherein
a first refractive index of the wall portion and a second refractive index of the colored layer are different from each other,
the wall portion includes a first opening corresponding to the first light-emitting element and a second opening corresponding to the second light-emitting element and includes a recessed portion that is recessed inside the wall portion between a top portion that is thickest in the wall portion and an end portion that is thinnest in the wall portion, and
the colored layer is in contact with the sealing layer though the first opening and the second opening and includes a curved surface that is in contact with recessed portion of the wall portion and protrudes toward the wall portion.
