ORGANIC LIGHT-EMITTING ELEMENT AND PRODUCTION METHOD THEREFOR

摘要

An organic light-emitting element having a substrate, an anode on the substrate, a bank layer on or above the substrate that has an opening above the anode, a hole transport layer in the opening that contains organic material, an organic light-emitting layer on the hole transport layer that contains organic light-emitting material, and a cathode above the organic light-emitting layer. A portion of the hole transport layer is located between a periphery of the organic light-emitting layer and a side surface of the bank layer facing the opening. Carrier mobility of the hole transport layer is 1.0×10−3(cm2/Vs) or less.

主权项

1. An organic light-emitting element comprising:
a substrate; a first electrode on the substrate; a bank layer on or above the substrate, the bank layer having an opening above the first electrode; an organic functional layer in the opening, the organic functional layer containing organic material; an organic light-emitting layer on the organic functional layer, the organic light-emitting layer containing organic light-emitting material; and a second electrode above the organic light-emitting layer, wherein a portion of the organic functional layer is located between at least a portion of a periphery of the organic light-emitting layer and a side surface of the bank layer facing the opening, and carrier mobility of the organic functional layer is 1.0×10−3 cm2/Vs or less.
