ORGANIC ELECTROLUMINESCENCE ELEMENT AND METHOD OF MANUFACTURING THEREOF |
摘要 |
An organic EL element comprises: an anode; a cathode; a functional layer including at least a light-emitting layer; a hole injection layer disposed between the anode and the functional layer; and a bank. The hole injection layer contains tungsten oxide. Tungsten atoms constituting the tungsten oxide include both tungsten atoms with a valence of six and tungsten atoms with a valence less than six. The hole injection layer includes a crystal of the tungsten oxide. A particle diameter of the crystal is on an order of nanometers. The hole injection layer has a recessed portion whose inner side surface has an upper edge that is one of (i) aligned with part of a lower edge of the bank, the part being in contact with the light-emitting layer, and (ii) in contact with a bottom surface of the bank.
