MATERIAL FOR ORGANIC ELECTROLUMINESCENT ELEMENT COATED WITH LOW-MOLECULAR WEIGHT MATERIAL, INK COMPOSITION FOR ORGANIC ELECTROLUMINESCENT ELEMENT AND ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a material for an organic EL element and the organic EL element that has a layer made of a low-molecular weight material formed by a wet deposition method, hardly crystallizes and has excellent characteristics such as high luminous efficiency, low voltage drive, high color purity, long life and high heat resistance, and to provide an ink composition for the organic EL element that ensures high solubility of the low-molecular material suitable for depositing a film composing the organic luminescent material and enables easy formation of a thin film through a wet process.;SOLUTION: The ink composition for the organic electroluminescent element comprises a perylene compound (A), a diketopyrrolopyrrole compound (B) and a solvent.;COPYRIGHT: (C)2011,JPO&INPIT
