Embodiment Construction

[0037] Hereinafter, embodiments of the present invention will be described in detail with reference to the following drawings.

[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 that provides the excitation current. FIG. 7A schematically shows an exploded view of a simplified structure of a passive matrix OLED 1000 . FIG. 7B schematically shows a simplified structure of an active matrix OLED 1001 . In both configurations, the OLEDs 1000 , 1001 comprise OLED pixels comprising an anode 1004 , a cathode 1006 and an organic layer 1010 built on a substrate 1002 . When an appropriate current is applied to the anode 1004, current flows through the ...

Abstract

The invention provides an organic light emitting display and manufacturing method thereof, wherein, Newton's ring is prevented by controlling pressure difference. The organic light emitting display includes: a first substrate including pixel area in which at least one organic light emitting diode (OLED) is formed and non-pixel area; a second substrate which attaches to an area including the pixel area of the first substrate; glass material arranged between the non-pixel area of the first substrate and the second substrate. At least one of the first substrate and the second substrate forms an outward protrusion.

Description

technical field [0001] The present invention relates to an organic light emitting display and a manufacturing method thereof, and more particularly, to an organic light emitting display capable of preventing Newton's rings from being generated by controlling a differential pressure and a manufacturing method thereof. Background technique [0002] Recently, organic light emitting displays have been widely used due to their relatively simple structure. An organic light emitting display is a self-luminous display in which an organic layer is used as an emission layer. Since the organic light emitting display does not require a backlight for emitting light like a liquid crystal display (LCD), the organic light emitting display is thin and lightweight. Accordingly, organic light emitting displays have been actively developed as display panels of portable electronic devices such as portable computers, mobile phones, portable game machines, and e-books. [0003] In an organic lig...
