Embodiment Construction

[0020] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0021] 2A to 2H are cross-sectional views illustrating a method of manufacturing an organic electroluminescent device according to the present invention.

[0022] Referring to FIG. 2A, a metal layer is formed on the first insulating substrate 100, after which the gate electrode 201, the power supply line 411 and the first dummy pattern 413a are formed. Here, an ALNd layer or a double metal layer of ALNd and Mo can be used as the metal layer.

[0023] Thereafter, a gate insulating layer 102 is formed on the entire surface of the first insulating substrate 100 . Subsequently, an amorphous silicon layer and a metal layer are formed on the entire surface of the first insulating substrate 100 . Then, etching...

Abstract

Provided are an organic electroluminescent device and a fabrication method thereof. The organic electroluminescent device includes a first substrate, a second substrate, an organic electroluminescent layer formed on the first substrate, a thin film transistor formed on the second substrate, and first and second seal lines attaching the first and second substrates to each other.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2007-0018843 filed on February 26, 2007, which is hereby incorporated by reference. technical field [0002] The present invention relates to an organic electroluminescent device, and more particularly, to an organic electroluminescent device and a manufacturing method thereof for improving the bonding characteristics of an upper substrate and a lower substrate and preventing external moisture from penetrating. Background technique [0003] Recently, many attempts to improve the display quality of flat panel displays and to provide large-sized displays have been effectively made. Among them, organic electroluminescent devices are self-luminous and display video images by exciting fluorescent materials with carriers such as electrons and holes. Electroluminescent devices are mainly classified into inorganic electroluminescent devices and organic electroluminescent devices. But inorganic electrolum...
