Abstract
A display panel comprises: a planarization layer that lies on a substrate and compensates for irregularities; an electrode pattern that lies on the planarization layer in a non-display area of the substrate and exposes at least part of the planarization layer; and a moisture-impermeable layer that covers the planarization layer exposed by the electrode pattern.
Claims6
A display panel, comprising:
- a planarization layer that lies on a substrate and forms a planar upper surface;
- an electrode pattern having electrode members positioned at first locations on the planarization layer in a non-display area of the substrate, and no electrode members at second locations;
- a moisture-impermeable layer that covers the planarization layer, the moisture-impermeable layer being in contact with the electrode members at the first locations and in contact with the planarization layer at the second locations;
- and
- an organic light-emitting diode that lies on the planarization layer in a display area, wherein a cathode of the organic light-emitting diode is in contact with the moisture-impermeable layer,
- wherein the moisture-impermeable layer is made of a conductive metal material, and the electrode pattern receives a low-level voltage and applies the same to the cathode.

A display panel, comprising:
- a planarization layer that lies on a substrate and forms a planar upper surface;
- an organic emissive layer overlying the planarization layer;
- an electrode pattern having electrode members positioned at first locations on the planarization layer in a non-display area of the substrate, and no electrode members at second locations;
- a moisture-impermeable layer that covers the planarization layer, the moisture-impermeable layer being in contact with a part of the organic emissive layer, in contact with the electrode members at the first locations, and in contact with the planarization layer at the second locations;
- and
- a cathode that overlies the organic emissive layer and the moisture-impermeable layer,
- wherein the moisture-impermeable layer is composed of an electrically conductive metallic aluminum.
