Abstract
A full color organic light emitting display device (OLED) and a method of fabricating the same are provided. The OLED includes an element substrate and an encapsulating substrate. The element substrate includes a color filter layer or a color conversion layer, as well as an organic layer with an emission layer that emits light of a single color. The encapsulating substrate includes a color filter or a color conversion layer and a moisture absorbent, and a the color filter or color conversion layer corresponds to the emission region. Accordingly, there is no need to have a separate process for the moisture absorbent and the color filter layer or the color conversion layer may be formed without using a shadow mask, so that a high resolution OLED may be advantageously realized.
Claims12
A method of fabricating a full color organic light emitting display device (OLED), comprising:
- forming either a first color filter layer or a first color conversion layer on an element substrate;
- forming a pixel electrode on the element substrate;
- forming an organic layer including at least an emission layer on the pixel electrode;
- forming a counter electrode on the organic layer;
- and
- forming either a second color filter layer or a second color conversion layer comprising a moisture absorbent on an encapsulating substrate corresponding to the element substrate,
- wherein either the first color filter layer or the first color conversion layer is formed directly on a first side of the element substrate, the pixel electrode is formed on a second side of the element substrate, and the first side differs from the second side, and
- wherein the moisture absorbent is formed only directly on either the second color filter layer or the second color conversion layer and is spaced apart from the counter electrode.
