MANUFACTURE OF ELECTRODE SUBSTRATE FOR DISPLAY

摘要

PROBLEM TO BE SOLVED: To prevent a conductive material from becoming uneven in film thickness from one end to the other end of a substrate by reducing the influence of the wiring resistance of an auxiliary electrode when the conductive material which electrically connects an auxiliary electrode and a main electrode is formed by electric plating using the auxiliary electrode as an electrode by the method for manufacturing an electrode substrate for a display element which is equipped with a main electrode and an auxiliary electrode on one surface of a substrate and has the auxiliary electrode embedded in a flattening film. SOLUTION: Base metal 12a is formed entirely on one top surface of the substrate 11, a hole 131a which penetrates an insulating film 131 formed on the metal from the side of the base metal 12a onto the top of the insulating film 131 is formed, and electric plating using the base metal 12a as an electrode is carried out to fill the hole 131a with the conductive material 15 so that it is exposed in the hole 131a. The base metal 12a is patterned as specified to form the auxiliary electrode 12.
