US 2009/0021158 A1 · Organic electroluminescence display device

Abstract

An active matrix organic electroluminescence display device is provided with a transparent pixel electrode (AD1) as an anode, a pixel separation film (BNK) positioned next to and over an outer edge of the pixel electrode AD1, a transparent pixel electrode (AD2) positioned over the pixel separation film (BNK), an organic electroluminescence layer positioned over the transparent electrode (AD2), and a shared electrode (CD), functioning as a cathode, positioned over the organic electroluminescence layer. The transparent pixel electrode (AD1) is composed of indium oxide or zinc oxide; the transparent electrode (AD2) is composed of indium oxide or zinc oxide; the resistivity of the transparent electrode (AD2) is greater than the resistivity of the transparent pixel electrode (AD1); and the transparent electrode (AD2) is positioned in a layer between the organic electroluminescence layer, and the pixel separation film (BNK) and the transparent pixel electrode (AD1), covering the entire display area.
