ORGANIC ELECTROLUMINESCENT DEVICE, LIGHT-EMITTING APPARATUS USING ORGANIC ELECTROLUMINESCENT DEVICE, AND ELECTRICAL APPLIANCE USING SUCH LIGHT-EMITTING APPARATUS

摘要

An organic light-emitting device is manufactured, which is formed laminating an electroluminescent layer (111) including an electroluminescent organic compound and a cathode (109) sequentially on anode (101). The electroluminescent layer (111) has a hole blocking layer (106), and this hole blocking layer (106) is formed of two or more kinds of materials. It is possible to manufacture a high-efficiency and high-reliability organic light-emitting device by introducing the hole blocking layer like this.
