Embodiment Construction

[0033] Hereinafter, the present invention will be described more fully with reference to the accompanying drawings, in which embodiments of the invention are shown. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the size and relative sizes of layers and regions are exaggerated for clarity. The same reference numerals refer to the same elements in the drawings.

[0034] It should be understood that when an element or layer is referred to as being "on" or "connected to" another element or layer, the element may be directly on the other element or layer. A layer is either directly connected to the other element or layer, or there may be intervening elements or layers in between. In contrast, when an element is ref...

Abstract

The invention provides display devices that minimize permeation of oxygen and moisture, as well as methods of manufacturing such display devices. A display device according to the present invention includes an insulating substrate, a cover substrate connected to the insulating substrate, and a display element positioned between the insulating substrate and the cover substrate. The display device further includes a first sealant along an edge of one of the insulating substrate and the cover substrate, the first sealant including a first part and a second part spaced apart from each other, a second sealant provided along the edge of the other of the insulating substrate and the cover substrate, the second sealant being arranged between the first part of the first sealant and the second part of the first sealant, and an encapsulation film interposed between the first sealants and the second sealant.

Description

technical field [0001] The present invention relates to a display device and a manufacturing method thereof, and more particularly, to a display device capable of preventing infiltration of oxygen and moisture and a manufacturing method thereof. Background technique [0002] Recently, organic light emitting diode (OLED) devices have attracted attention and interest in the flat panel display device industry because flat panel display devices require low power, light weight, slim shape, wide viewing angle, and high-speed response. OLED devices include a plurality of thin film transistors and pixel electrodes. Each thin film transistor may include a gate electrode, a source electrode and a drain electrode, and each pixel electrode is connected to the thin film transistor. Walls provided between the pixel electrodes separate the pixel electrodes. Each pixel electrode has a light emitting layer formed thereon, and each light emitting layer has a common e...
