Embodiment Construction

[0027] Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0028] Hereinafter, various embodiments of the present invention will be described with reference to the accompanying drawings.

[0029] The light emitting display described below may be implemented as a TV, a video player, a personal computer (PC), a home theater, a smart phone, a virtual reality (VR) device, and the like. In the following description, an organic light emitting display based on an organic light emitting diode (light emitting device) is described as an example of a light emitting display. However, light-emitting displays can be realized based on inorganic light-emitting diodes.

[0030] figure 1 is a schematic block diagram of an organic light-emitting display, figure 2 is the schematic circuit diagram of the sub-pixel, image 3 is showing figure 2 An example of a part circuit configuration, Figure 4 is an exem...

Abstract

A display device includes a display area and a non-display area disposed at a substrate, a moisture transfer delay portion, and a protective layer. The non-display area is arranged outside the displayarea. The moisture transfer delay portion includes a trench formed at the non-display region to surround the display region and having a cross-section having a lower width greater than an upper width. The protective layer covers the display area and the non-display area in which the moisture transfer delay portion is formed.

Description

technical field [0001] The present invention relates to a display device. Background technique [0002] An organic light emitting device is a typical example of a flat panel display device. An organic light emitting device may be configured by interposing an organic thin film layer including an organic light emitting layer between an anode layer and a cathode layer on a substrate. Organic light emitting devices have advantages of being driven at low voltage and realized in a thin shape, and thus, organic light emitting devices are attracting attention as next-generation flat panel display devices. [0003] Organic light emitting devices are susceptible to external materials such as moisture and oxygen, and thus require a sealing process to protect the devices. For this reason, a protective layer is conventionally formed on a transparent substrate forming an organic light emitting device in order to isolate the organic light emitting device, especially an organic thin layer...
