Patent ID: 6949328

Claim:
A method for manufacturing an electroluminescent element comprising at least: a hole injecting layer forming process of forming a hole injecting layer, which can be decomposed and removed by the action of a photocatalyst in irradiation with energy, on a first electrode layer formed side surface of a base material with the first electrode layer formed on the surface in a pattern; a decomposition removing process of using a photocatalyst treatment layer substrate having at least a photocatalyst treatment layer containing a photocatalyst formed on a substrate, placing the base material with the hole injecting layer formed thereon and the photocatalyst treatment layer substrate with a gap of 200 μm or less so that the photocatalyst treatment layer substrate and the hole injecting layer are facing to each other, and then, decomposing and removing the hole injecting layer in between the first electrode layers, in a pattern, on the base material with the hole injecting layer formed thereon by irradiating with energy from predetermined direction; a light emitting layer forming process of forming the light emitting layer on the pattern formed hole injecting layer remaining on the base material; and a second electrode layer forming process of forming the second electrode layer on the light emitting layer; wherein a contact angle to a liquid of the surface of the hole injecting layer is smaller than the contact angle to a liquid of the surface bared by removing the hole injecting layer in the decomposition removing process.
