Application Number: JP,2024-216393
Category (FI): G09F9/30,330,G09F9/33,H10H20/813,H10H20/831,H10H20/832,H10H20/854,H10H20/857,H10H29/34,H10H29/49,H10H29/854
Stage: PROBLEM TO BE SOLVED: To provide a display apparatus capable of increasing an area of each sub-pixel in a restricted pixel area.SOLUTION: A light-emitting element includes: first, second and third light-emitting stacks each including a first conductive type semiconductor layer, an active layer, and a second conductive type semiconductor layer, which are stacked in the order; a first lower contact electrode that is in ohmic contact with the first light-emitting stack; a second lower contact electrode that is in ohmic contact with the second conductive type semiconductor layer of the second light-emitting stack; and a third lower contact electrode that is in ohmic contact with the second conductive type semiconductor layer of the third light-emitting stack. The second light-emitting stack is arranged between the first light-emitting stack and the third light-emitting stack, the first lower contact electrode is arranged between the first light-emitting stack and the second light-emitting stack, and the second and third lower contact electrodes are arranged between the second light-emitting stack and the third light-emitting stack. The first, second and third lower contact electrodes include a transparent conductive oxide layer, and the thickness of the second lower contact electrode or the third lower contact electrode is greater than the thickness of the first lower contact electrode.SELECTED DRAWING: Figure 2 (Grant)
