Embodiment Construction

[0063] For simplicity and clarity of illustration, elements in the figures have not necessarily been drawn to scale. The same reference numbers in different drawings identify the same or similar elements and thus perform similar functions. Furthermore, descriptions and details of well-known steps and elements are omitted for simplicity of the description. Furthermore, in the following detailed description of the present disclosure, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, it is understood that the present disclosure may be practiced without these specific details. In other instances, well-known methods, operations, components, and circuits have not been described in detail as not to unnecessarily obscure aspects of the present disclosure. Examples of various embodiments are further illustrated and described below. It should be understood that the description herein is not intended to limit the c...

Abstract

A display device includes: an array substrate having a display area and a non-display area positioned outside the display area, and having a light emitting array; and a sealing structure disposed on the array substrate, in which the sealing structure seals the light emitting array and fixes the plate-shaped reinforcing substrate facing the sealing structure to the array substrate. In this aspect, the sealing structure includes a first adhesive layer facing the array substrate, a second adhesive layer facing the reinforcement substrate, and a barrier layer disposed between the first adhesive layer and the second adhesive layer. Thus, the thickness of the sealing structure is greater than the critical thickness to avoid process defects in a single layer made of an adhesive material. According to the sealing structure, the reduction of the fixing reliability of the reinforcing substrate with relatively large thickness is avoided. Therefore, the rigidity and heat dissipation effect due to the reinforcement of the substrate are sufficient.

Description

technical field [0001] The present disclosure relates to a display device including a sealing structure for sealing a light emitting element. Background technique [0002] Display devices are applied to various electronic devices such as televisions, mobile phones, notebook computers, and tablet computers. For this reason, research is continuing to develop thinner, lighter, and lower power consumption display devices. [0003] Examples of the display device include a liquid crystal display device (LCD), a plasma display device (PDP), a field emission display device (FED), an electrowetting display device (EWD), and an electroluminescent display device (ELDD), or an organic light emitting display device (OLED), etc. [0004] An organic light emitting display device (OLED) includes a plurality of pixel regions arranged in a display region in which an image is displayed, and a plurality of organic light emitting elements respectively corresponding to the plurality of pixel re...
