Organic EL display device and method of manufacturing an organic EL display device
View Patent ↗An organic EL display device includes in order from a substrate side: a metal layer; an insulating layer formed on the metal layer; a first electrode layer formed on the insulating layer; an organic layer formed on the first electrode layer; and a second electrode layer formed on the organic layer. The metal layer is for use as a reflective layer configured to reflect, on a surface of the metal layer, light generated from the organic layer by applying a voltage between the first electrode layer and the second electrode layer.
1. An organic EL display device comprising, in order from a substrate side:
a metal layer;
an insulating layer formed on the metal layer;
a first electrode layer formed on the insulating layer;
an organic layer formed on the first electrode layer; and
a second electrode layer formed on the organic layer,
wherein the metal layer is formed so as to have structure in which an Al layer, a Mo layer, and an ITO layer are laminated, and
wherein the metal layer is for use as a reflective layer configured to reflect, on a surface of the Al layer, light generated from the organic layer by applying a voltage between the first electrode layer and the second electrode layer.
2. The organic EL display device according to claim 1 ,
wherein the metal layer is further for use as auxiliary wiring of the second electrode layer.
3. The organic EL display device according to claim 1 ,
wherein the metal layer and the first electrode layer sandwich the insulating layer to form an additional capacitor.
4. The organic EL display device according to claim 1 ,
wherein the first electrode layer is formed of ITO.
5. A method of manufacturing an organic EL display device, comprising, in order from a substrate side:
forming a metal layer;
forming an insulating layer on the metal layer;
forming a first electrode layer on the insulating layer;
forming an organic layer on the first electrode layer; and
forming a second electrode layer on the organic layer,
wherein the metal layer is formed so as to have structure in which an Al layer, a Mo layer, and an ITO layer are laminated, and
wherein the metal layer is for use as a reflective layer configured to reflect, on a surface of the Al layer, light generated from the organic layer by applying a voltage between the first electrode layer and the second electrode layer.
