MOISTURE-ABSORPTION PASSIVATION STRUCTURE OF ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a moisture-absorption passivation film suitable for an organic light-emitting element in a high-grade active matrix method and a passive matrix method; to provide a moisture-adsorption passivation structure to be adapted to a surface light-emitting type organic electroluminescent display (OELD).

SOLUTION: The moisture-absorption passivation structure for covering a display area of the organic electroluminescent display device (OELD) includes at least one buffer layer, moisture-absorption material layer and passivation layer. The moisture-absorption material is used to absorb a small amount of moisture generated inside the OELD and moisture intruding from the outside of the passivation layer.
