METHOD OF MANUFACTURING ORGANIC LIGHT EMITTING DIODE ELECTROLUMINESCENT DISPLAY DEVICE

摘要

PURPOSE: A method for manufacturing an organic light emitting display device is provided to prevent the dopant of a hole transport layer from being redeposited on a light emitting layer and diffused from a barrier layer to the light emitting layer. CONSTITUTION: A hole transport layer is formed on a substrate in a first chamber(S1). The substrate having the hole transport layer is moved to a second chamber(S2). A barrier layer is formed on the upper part of the hole transport layer in the second chamber(S3).
