Publication number: 20240090249Abstract: An organic EL device includes organic layers, an anode electrode, a cathode electrode, and an insulating layer covering a part of the anode electrode. The anode electrode is disposed above a bank layer and in an opening of the bank layer. The organic layers cover the anode electrode and a part of the insulating layer. The anode electrode includes a lower conductive layer, a reflective metal layer that reflects light coming from the organic layers, and a light-transmissive upper conductive layer layered in this order toward the cathode electrode. The upper conductive layer includes a first upper conductive layer connected to the organic layers and a second upper conductive layer covered with the insulating layer. The second upper conductive layer has a lower oxygen content than the first upper conductive layer. The second upper conductive layer has a higher resistivity than the first upper conductive layer.Type: ApplicationFiled: September 1, 2023Publication date: March 14, 2024Inventors: Tomohide SHINDOU, Shigeru MORI
