Abstract
Official abstract text for this publication.
An organic light emitting diode display according to an exemplary embodiment includes: a substrate; a pixel formed on the substrate and including a pixel area displaying an image and a peripheral area adjacent to the pixel area; an insulating layer at the pixel area and the peripheral area on the substrate; a first electrode at the pixel area on the insulating layer; an organic emission layer on the first electrode and extending to the peripheral area; a second electrode on the organic emission layer and disposed in the pixel area and the peripheral area; an auxiliary electrode in the peripheral area on the substrate and partially exposed by a first opening formed in the insulating layer; and an auxiliary member disposed on the auxiliary electrode and in contact with an upper surface of the auxiliary electrode exposed by the first opening.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for manufacturing an organic light emitting diode display, comprising: preparing a substrate; forming a thin film transistor including a semiconductor layer, a gate electrode on the semiconductor layer, and a source electrode and a drain electrode connected to the semiconductor layer on the substrate; forming an auxiliary electrode supplying a common voltage on the substrate; forming an insulating layer on the thin film transistor and the auxiliary electrode and exposing parts of the drain electrode and the auxiliary electrode; forming a first electrode on the insulating layer and in contact with the drain electrode; forming an auxiliary member in contact with the auxiliary electrode through a first opening formed in the insulating layer; forming an organic emission layer on the first electrode and the auxiliary member; removing a part of the organic emission layer to expose a part of the auxiliary member; and forming a second electrode on the organic emission layer. 2. The method of claim 1 , wherein the removing of the part of the organic emission layer is performed by using a laser. 3. The method of claim 1 , wherein the removing of the part of the organic emission layer includes forming a second opening by removing the part of the organic emission layer. 4. The method of claim 3 , wherein the second opening has a circular shape. 5. The method of claim 1 , further comprising forming a pixel definition layer having a third opening exposing the part of the auxiliary member and a fourth opening exposing the part of the first electrode. 6. The method of claim 1 , wherein: the source electrode, the drain electrode, and the auxiliary electrode are formed with the same layer. 7. The method of claim 1 , wherein the first electrode and the auxiliary member are formed with the same layer. 8. The method of claim 1 , wherein the auxiliary member is in contact with an entire upper surface of the auxiliary electrode exposed by the first opening.
