Embodiment Construction

[0041] Hereinafter, exemplary embodiments of the present invention will be described in detail.

[0042] In organic light-emitting diode (OLED) technology, the encapsulation process is the core technology that determines the lifetime and reliability of OLEDs, and OLED materials can cause various problems, such as inducing deformation of organic material layers and electrodes and Lifespan decline, which is caused by the characteristics of OLED materials that are extremely intolerant to moisture and oxygen. Therefore, in OLEDs, an encapsulation step that blocks external air is absolutely necessary.

[0043] An organic light emitting diode in the related technical field and a manufacturing method thereof are schematically illustrated in figure 1 and Figure 4 middle. In the organic light emitting diode of the related art, in order to expose the electrode pad ends 50 and 55, a method of cutting the sealing layer 30 and laminating the sealing layer 30 on the organic light emitti...

Abstract

The present invention relates to an organic light-emitting device and a method for manufacturing same. Specifically, the organic light-emitting device according to the present invention comprises: a substrate; an organic light-emitting unit including a first electrode, an organic material layer, and a second electrode, which are sequentially stacked on the substrate; an encapsulation unit which seals the outer side of the organic light-emitting unit. The encapsulation unit includes a sealing layer contacting the outer side of the organic light-emitting unit, an insulating layer mounted on the sealing layer, and a metal pattern layer mounted between the sealing layer and the insulating layer.

Description

【Technical field】 [0001] This application claims priority from Korean Patent Application No. 10-2013-0099236 filed with the Korean Patent Office on Aug. 21, 2013, the entire contents of which are incorporated herein by reference. [0002] The present application relates to an organic light emitting diode and a preparation method thereof. 【Background technique】 [0003] An organic light emitting diode is a light emitting device that emits light when holes and electrons are injected into a light emitting layer formed between the electrodes through electrodes and the injected holes and electrons generate excitons to be dissipated. [0004] Compared with liquid crystal displays in related technical fields, organic light emitting diodes have self-emission characteristics, so organic light emitting diodes have the advantages of small thickness, low energy consumption, excellent viewing angle, and high response speed. In addition, OLEDs have the advantages of low power consumption...
