Original Abstract Submitted
The light-emitting device has: a display region; a peripheral region; a first light-emitting element having a light-emitting region in which a lower electrode, a light-emitting layer, and an upper electrode are laminated; a first laminated section, between the substrate and the lower electrode of the first light-emitting element, in which there are laminated a first high-reflection layer and a first low-reflection layer that has a lower reflectance than the first high-reflection layer; a peripheral laminated section, in the peripheral region, in which there are laminated on the substrate; a peripheral lamination layer in which a peripheral high-reflection layer and a peripheral low-reflection layer that has a lower reflectance than the peripheral high-reflection layer are laminated. For at least a portion of the first laminated section that overlaps in plan view with the light-emitting region, the first low-reflection layer has an opening such that the first high-reflection layer is exposed.
