Title:
有機電界発光素子の製造方法
Document Type and Number:
Japanese Patent JP5506475
Kind Code:
B2
Abstract:
Provided is a method for producing an organic electroluminescence device which contains an anode, a cathode and an organic layer between the anode and the cathode where the organic layer contains a light-emitting layer and an adjacent layer adjacent to the light-emitting layer, the method including: applying to the adjacent layer a coating liquid prepared by dissolving or dispersing a light-emitting material and a host material in a solvent, and heating the coating liquid applied to the adjacent layer at a temperature higher than a melting temperature of the host material and higher than a boiling point of the solvent, to thereby form the light-emitting layer, wherein a difference as an absolute value between contact angle A (°) of the light-emitting layer with respect to pure water and contact angle B (°) of the adjacent layer with respect to pure water is 13 (°) or smaller.
