Zusammenfassung: | To suppress variation in luminance in a light-emitting region.SOLUTION: A first conductive part 210 surrounds a light-emitting element 140. The first conductive part 210 contains a material having resistance lower than that of a material of a first electrode 110, and it is connected to the first electrode 110. A second conductive part 230 is located around the light-emitting element 140, and it is connected to a second electrode 130. The second electrode 130 is supplied with potential from a first portion P1 on an edge E of the light-emitting element 140. The first portion P1 is located at a position closest to an intersection P of a plurality of virtual lines IL each bisecting an area of the light-emitting element 140 (a light-emitting region 142).SELECTED DRAWING: Figure 1
【課題】発光領域の輝度のばらつきを抑える。【解決手段】第1導電部210は、発光素子140を囲んでいる。第1導電部210は、第1電極110の材料より低抵抗の材料を含んでおり、第1電極110に接続している。第2導電部230は、発光素子140の周囲に位置しており、第2電極130に接続している。第2電極130は、発光素子140の縁Eの第1部分P1から電位を供給されている。第1部分P1は、発光素子140(発光領域142)の面積をそれぞれ二等分する複数の仮想線ILの交点Pから最も近くの位置にある。【選択図】図1 |
