ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE AND MANUFACTURING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To control electrical color mixture at low cost.SOLUTION: An organic electroluminescence display device manufacturing method comprises the steps of: preparing a first substrate 10 on which a plurality of pixel electrodes 18 are provided; partitioning a plurality of pixel regions by being placed on a circumference of each pixel electrode 18 to form a bank layer 20 to include a metal ion adsorbent; forming an organic electroluminescence film 22 by being placed on the bank layer 20 and the plurality of pixel electrodes 18 and so as to include a metal complex which is a compound obtained by coordinating a ligand with a metal ion; and forming a common electrode 32 on the organic electroluminescence film 22 in which the organic electroluminescence film 22 is formed in a manner such that a concentration of the metal ion becomes lower above the bank layer 20 by the metal ion absorbent.
