Abstract

See full text

A light shielding layer (200) is located between a plurality of light-emitting regions (101) when seen in a direction perpendicular to a substrate (100). The light shielding layer (200) includes a light reflection layer (202) and a light absorbing layer (204). The light absorbing layer (204) is located closer to the substrate (100) side in a thickness direction than the light reflection layer (202), and has a light reflectance lower than that of the light reflection layer (202). Further, when seen in the direction perpendicular to the substrate (100), an end of the light reflection layer (202) is located further inside of the light shielding layer (200) than an end of the light absorbing layer (204).
