Problems solved by technology

[0003] Since liquid crystal display devices are passive devices rather than self-emitting devices, they have limitations in brightness, contrast, viewing angle, size, etc.
Although PDPs are self-emitting devices, they are heavy, consume a lot of power, and are complex to manufacture compared to other flat panel display devices

Embodiment Construction

[0037] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. In the drawings, the thicknesses of layers and regions are exaggerated for clarity. The same reference numerals are used throughout the specification to refer to the same elements.

[0038] An organic light emitting display (OLED) is a display device that includes an array of organic light emitting diodes. Organic light emitting diodes are solid state devices comprising organic materials adapted to generate and emit light when an appropriate electrical potential is applied.

[0039] OLEDs can generally be divided into two basic types according to the configuration in which the excitation current is supplied. Figure 5 An exploded view of a simplified structure of a passive matrix type OLED 1000 is schematically shown. Image 6 A simplified structure of an active matrix type OLED 1001 is schematicall...

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.

Description

technical field [0001] The present invention relates to an organic light emitting display device (OLED) and a manufacturing method thereof, and more particularly, to an OLED having improved adhesion characteristics and a manufacturing method thereof. Background technique [0002] Recently, flat panel displays, such as liquid crystal display devices, organic light emitting display devices, and plasma display panels (PDPs), which do not have some of the disadvantages of display devices such as cathode ray tubes (CRTs), have drawn attention. [0003] Since liquid crystal display devices are passive devices rather than self-emitting devices, they have limitations in brightness, contrast, viewing angle, size, and the like. Although PDPs are self-luminous devices, they are heavy, consume a lot of power, and are complicated to manufacture compared to other flat panel display devices. [0004] On the other hand, since the organic light-emitting device is a self-luminous device, it ...
