ELECTROLUMINESCENT ELEMENT

摘要

An electroluminescent element capable of being produced in a short time, wherein a layer constituting a luminescent area, generally believed to defy patterning, is formed by being patterned uniformly and in a highly membranous form, and the patterning is permitted within a wide range of viscosity and with a wide−range choice of a solvent. An electroluminescent element comprising a hole transportation layer (4) and an electron transportation layer (5) provided, as layers having luminescent areas, between a transparent pixel electrode (2) and cathodes (9),(10), and (13), characterized in that at least the electron transportation layer (5) is formed by having its composition material transferred by a relief print reversing offset method.
