キャリア注入量制御電極を有する有機エレクトロルミネセンス素子

Japanese Patent JP7364286

B2

An organic electroluminescence element (200a) includes a first electrode (102), a third electrode (118) including a region overlapping the first electrode, a first insulating layer (104) between the first electrode (102) and the third electrode (118), a second insulating layer (120) between the first insulating layer (104) and the third electrode (118) and including an opening, an electron transfer layer (106) between the first insulating layer (104) and the third electrode(118), a light emitting layer (112), containing an organic electroluminescence material, between the electron transfer layer (106) and the third electrode (118), and a second electrode (108) located between the first insulating layer (104) and the second insulating layer (120) and electrically connected with the electron transfer layer (106). The organic electroluminescence element (200a) includes an overlap region where the third electrode (118), the light emitting layer (112), the electron transfer layer (106), the first insulating layer (104) and the first electrode (102) have overlapping region overlapping in the opening of the second insulating layer (120).
