Problems solved by technology

[0005] However, when the thickness of the substrate of the light-emitting display is reduced to only about 0.3 mm to reduce the thickness of the light-emitting display, it is difficult to maintain the mechanical integrity of the device under stress such as dropping and twisting
Lack of mechanical integrity compromises device hermetic state, shortening OLED lifetime

Abstract

The present invention is to provide an organic light emitting display and a method of manufacturing the same, the light emitting display including: a first substrate on which a plurality of light emitting devices are formed; a second substrate disposed to face the first substrate; a dam member disposed between the first substrate and the second substrate to surround the plurality of light emitting devices; an inorganic sealing material disposed between the first substrate and the second substrate on an outward side of the dam member and attaching the first substrate and the second substrate; and a filling material provided between the first substrate and the second substrate on an inward side of the dam member and formed of at least one inert liquid selected from the group consisting of perfluorocarbon and fluorinert.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2008-0106221 filed with the Korean Intellectual Property Office on October 29, 2008, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a light-emitting display and a manufacturing method thereof, more particularly, to a light-emitting display having an inert liquid filling material interposed between a sealing substrate and a light-emitting device formed thereon between the substrates. Background technique [0003] Since a light emitting device such as an organic light emitting diode (OLED) includes an organic material susceptible to moisture or oxygen, it is necessary to protect the OLED from moisture or oxygen with a sealing member. [0004] Since light-emitting displays using OLEDs generally have wide viewing angles, high contrast ratios, and fast response speeds as well as low power consumption, light-emitting displays ...
