ABSTRACT:
An EL element capable of: preventing the state in which number of excessive layers are laminated on each light emitting part formed in a pattern at the time of forming the light emitting parts using the photolithography method; executing the peeling treatment easily and quickly in the excessive layer peeling process; and preventing generation of color mixture or pixel narrowing derived from the elution of the patterned light emitting part into the light emitting layer coating solution to be coated later, at the end part thereof, at the time of coating a light emitting layer coating solution. In order to achieve the above mentioned object, the present invention provides a method for manufacturing an electroluminescent element using a photolithography method.
