Abstract
An organic light emitting diode, a method for manufacturing an organic light emitting diode, and an organic light emitting diode display, the OLED including a substrate; a first electrode on the substrate, the first electrode including a sequentially stacked conductive layer and transparent protective layer; a hole transfer layer on a surface of the transparent protective layer; an organic emitting layer on the hole transfer layer, the organic emitting layer emitting light having a specific color; a common layer on the organic emitting layer; and a second electrode on the common layer.
Claims20
An organic light emitting diode, comprising:
- a substrate;
- a first electrode on the substrate, the first electrode including a sequentially stacked conductive layer and transparent protective layer;
- a hole transfer layer, the hole transfer layer being a surface-treated portion of the transparent protective layer;
- an organic emitting layer on the hole transfer layer, the organic emitting layer emitting light having a specific color;
- a common layer on the organic emitting layer;
- and
- a second electrode on the common layer.
A method for manufacturing an organic light emitting diode, the method comprising:
- forming a first electrode such that the first electrode includes a conductive layer and a transparent protective layer sequentially stacked on a substrate;
- surface-treating an upper surface of the transparent protective layer to form a hole transfer layer;
- forming an organic emitting layer on the hole transfer layer;
- forming a common layer on the organic emitting layer;
- and
- forming a second electrode on the common layer.
An organic light emitting diode display, comprising:
- a substrate;
- at least one thin film transistor (TFT) on the substrate;
- an organic light emitting diode (OLED) on the substrate and connected to the at least one TFT to generate light having a specific color;
- and
- an encapsulating member encapsulating the OLED,
- wherein the OLED includes:
- a first electrode that includes sequentially stacked conductive layer and transparent protective layer;
- a hole transfer layer, the hole transfer layer being a surface-treated portion of the transparent protective layer;
- an organic emitting layer on the hole transfer layer;
- and
- a second electrode on the organic emitting layer.
