Abstract
Official abstract text for this publication.
An organic EL element includes: a first electrode that is a metal layer; a transparent conductive layer containing indium zinc oxide; and a light-emitting layer, wherein the first electrode, the transparent conductive layer, and the light-emitting layer are stacked, and a ratio of zinc to indium in a vicinity of an interface of the transparent conductive layer is lower than or equal to 0.25, the interface being closer to the light-emitting layer.
First claim
Opening claim text (preview).
1 . A light-emitting element comprising: a metal layer; a transparent conductive layer containing indium zinc oxide; and a light-emitting layer, wherein the metal layer, the transparent conductive layer, and the light-emitting layer are stacked, and a ratio of zinc to indium in a vicinity of an interface of the transparent conductive layer is lower than or equal to 0.25, the interface being closer to the light-emitting layer. 2 . The light-emitting element according to claim 1 , wherein the transparent conductive layer is approximately 5 nm or less in thickness. 3 . The light-emitting element according to claim 1 , wherein the metal layer contains aluminum. 4 . The light-emitting element according to claim 1 , further comprising a hole injection layer between the transparent conductive layer and the light-emitting layer. 5 . The light-emitting element according to claim 4 , wherein the hole injection layer contains an organic amine. 6 . The light-emitting element according to claim 4 , further comprising an electron block layer between the hole injection layer and the light-emitting layer. 7 . A display device, comprising the light-emitting element according to claim 1 . 8 . A method for manufacturing a light-emitting element, the method comprising: forming a metal layer; forming a transparent conductive layer above the metal layer, the transparent conductive layer containing indium zinc oxide; oxidizing the metal layer; and forming a light-emitting layer above the transparent conductive layer, wherein a ratio of zinc to indium in a vicinity of an interface of the transparent conductive layer is lower than or equal to 0.25, the interface being closer to the light-emitting layer. 9 . The method according to claim 8 , wherein the oxidizing includes baking the metal layer or irradiating the metal layer with ultraviolet rays. 10 . The method according to claim 8 , wherein the oxidizing is performed after the forming of a transparent conductive layer. 11 . The method according to claim 8 , wherein the oxidizing is performed between the forming of a metal layer and the forming of a transparent conductive layer. 12 . The method according to claim 8 , wherein in the forming of a transparent conductive layer, the transparent conductive layer is formed with a thickness of approximately 5 nm or less. 13 . The method according to claim 8 , wherein the metal layer contains aluminum. 14 . The method according to claim 8 , further comprising forming a hole injection layer between the forming of a transparent conductive layer and the forming of a light-emitting layer. 15 . The method according to claim 14 , wherein the hole injection layer contains an organic amine. 16 . The method according to claim 14 , further comprising forming an electron block layer between the forming of a hole injection layer and the forming of a light-emitting layer.
