Method of manufacturing a conductive via in an organic light emitting display

摘要

A manufacturing method of an organic light emitting display includes preparing a substrate including a cathode line and forming an anode electrode on the substrate, the anode electrode being insulated from the cathode line. The method also includes forming an insulating layer having a first opening exposing a portion of the cathode line and a second opening exposing a portion of the anode electrode on the substrate, forming an organic layer on the insulating layer, and forming an electrical connection portion electrically connected to the cathode line. The electrical connection portion is formed in this method by supplying a conductive solution that dissolves the organic layer in an area of the organic layer corresponding to the first opening, and the manufacturing method also includes forming a cathode electrode overlapping with the electrical connection portion.

1. A method of manufacturing an organic light emitting display, comprising:
preparing a substrate including a cathode line; forming a plurality of anode electrodes on the substrate, the anode electrodes being insulated from the cathode line; forming a pixel definition layer having a first opening and a plurality of second openings on the substrate, the first opening exposing a portion of the cathode line and each of the second openings exposing a portion of a corresponding one of the anode electrodes, the pixel definition layer covering a portion of the cathode line, and the second openings being arranged in a matrix shape along a plan view of the organic light emitting display; forming an organic layer on the pixel definition layer, the organic layer overlapping the first opening and the second openings; forming an electrical connection portion electrically connected to the cathode line by supplying a conductive solution that dissolves the organic layer in an area of the organic layer corresponding to the first opening; and forming a cathode electrode on the organic layer, the cathode electrode being electrically connected to the electrical connection portion.
