A method for manufacturing an electroluminescent element includes forming a hole injecting layer on a first electrode layer a base material with the first electrode layer formed in a pattern; a decomposition removing process of using a photocatalyst treatment layer substrate having at least a photocatalyst treatment layer, placing the base material and the photocatalyst treatment layer substrate facing each other with a gap of 200 m or less, decomposing and removing the hole injecting layer, in a pattern, on the base material by irradiating from predetermined direction; forming a light emitting layer on the pattern formed hole injecting layer remaining on the base material; and forming a 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.
