Title:
METHOD FOR MANUFACTURING ORGANIC LIGHT-EMITTING DEVICE, ORGANIC LIGHT-EMITTING DEVICE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/060854
Kind Code:
A1
Abstract:
Disclosed is a method for manufacturing an organic light-emitting device which comprises
an organic light-emitting element whose light-emitting layer can be composed
not only of a solid light-emitting material but also of a liquid or semisolid light-emitting
material. Also disclosed are an organic light-emitting device produced by such
a manufacturing method and having good characteristics, and an electronic device
having high reliability. Specifically disclosed is a display (organic light-emitting
device) comprising a plurality of organic light-emitting elements (organic
EL elements) each having a cathode, an electron transport layer, a light-emitting
layer, a hole transport layer and an anode. This display is obtained by forming
the organic EL elements by such a process wherein the anode and the hole transport
layer are formed on an upper substrate and the cathode and the electron transport
layer are formed on a TFT circuit substrate respectively by a liquid phase deposition
method or a vapor phase deposition method, next the upper substrate and the TFT
circuit substrate are bonded together so as to have a space between them, and then
the light-emitting layer is formed by injecting a light-emitting material into
the space.
