Organic light emitting display and method of fabricating the same
First Claim
1. An organic light emitting display device comprising:
- a first substrate;
an second substrate;
an integrated structure formed on the first substrate, wherein the integrated structure comprises a non-conductive inorganic material layer and an array of organic light emitting pixels formed over the non-conductive inorganic material layer; and
a frit seal interposed between and interconnecting the first and second substrates while surrounding the array, the frit seal having a first surface facing the first substrate and a second surface facing the second substrate, wherein the second surface contacts the non-conductive inorganic material layer.

Abstract
An OLED having an improved adhesion characteristic and a method of fabricating the same are provided. The OLED includes: a substrate having a pixel region and a non-pixel region except the pixel region; and an encapsulation substrate for encapsulating the substrate. The pixel region includes: a thin film transistor including a semiconductor layer, a gate electrode, and source and drain electrodes; a first electrode electrically connected with the thin film transistor; a pixel defining layer disposed on the first electrode; an organic layer having at least an emissive layer formed on the first electrode and the pixel defining layer; a second electrode disposed on the organic layer; and at least one inorganic layer. The non-pixel region includes at least one inorganic layer, and a frit disposed on the inorganic layer to encapsulate the substrate and the encapsulation substrate.
