US 8,409,884 B2 · Process for producing organic electroluminescent panel

Abstract

The process for producing an organic EL panel according to the present invention is a process for producing an organic electroluminescent panel by forming an organic electroluminescent element on an ultrathin glass plate by vacuum deposition method, including forming electrodes on the ultrathin glass plate, by temporarily fixing the ultrathin glass plate to a supporting plate via a double-sided adhesive tape having a thermal release adhesive layer formed at least on one face of the base material layer, containing heat-expandable microspheres that start expansion and/or foaming at temperature higher than the vacuum deposition temperature.

A process for producing an organic electroluminescent panel by forming an organic electroluminescent element on an ultrathin glass plate by a vacuum deposition method,

comprising the steps of temporarily fixing the ultrathin glass plate having a thickness of 10 to 150 μm to a supporting plate via a double-sided adhesive tape having a thermal release adhesive layer formed at least on one face of a base material layer, and containing heat-expandable microspheres that start expansion and/or foaming at temperature higher by 20° C. or more than a vacuum deposition temperature;
and forming electrodes on the ultrathin glass plate.

Dependencies are inferred from the claim text.
