Document Type and Number:

Japanese Patent JP5682956

Kind Code:

B2

Abstract:

Disclosed are an image display device and an organic EL element, each of which involves at least a polyimide film substrate and an ITO electrode formed on the substrate, wherein the ITO electrode is a polycrystalline ITO electrode and the polyimide film contains a repeating unit represented by formula [1] in an amount of at least 10 mol%. Each of the image display device and the organic EL element involves a flexible polyimide film and has excellent element properties including light emission luminance. (In the formula, R1 and R2 independently represent a hydrogen atom, a halogen atom, or an alkyl group having 1 to 5 carbon atoms; R3, R4 and R5 independently represent a hydrogen atom, a halogen atom, an alkyl group having 1 to 10 carbon atoms, an alkenyl group having 2 to 5 carbon atoms, an alkoxyl group having 1 to 5 carbon atoms, a cycloalkyl group having 3 to 7 carbon atoms, a nitril group, or a carboxyl group; and n represents a integer.)
