Title:
ORGANIC EL ELEMENT AND ITS MANUFACTURING METHOD AS WELL AS ORGANIC EL DISPLAY
Document Type and Number:
Japanese Patent JP2004303471
Kind Code:
A
Abstract:
To provide an organic EL element and its manufacturing method as well as an organic EL display capable of attaining high adhesion between an organic layer and an inorganic layer by reducing a residual solvent without detriment to intrinsic characteristics of the organic layer.
In the organic EL element 9 provided with a base plate 1, an electrode layer 2, an organic layer 3, and an electrode layer 4, the organic layer 3 is made to contain a polymer satisfying a formula (1): 20≤Y/(X+Y)×100≤70 [where, X and Y denote the total number of atoms involved in a π bonding and the total number of atoms only involved in a σ bonding, respectively, out of a carbon atom, nitrogen atom, oxygen atom, and sulfur atom constituting the polymer.].
