ORGANIC ELECTROLUMINESCENT DISPLAY PANEL AND MOISTUREPROOF SUBSTRATE

摘要

This invention provides an organic EL display panel and a moistureproof substrate that can withstand long-term use. The organic EL display panel comprises a substrate, an organic electroluminescent element supported on the substrate, and a gas barrier layer provided between the substrate and the organic electroluminescent element. The gas barrier layer comprises two or more inorganic material films and one or more organic material film each provided between the inorganic material films. The thickness of at least one layer of the organic material films is at least five times larger than the thickness of the inorganic material films adjacent to the organic material film on the substrate side.
