Abstract

Provided is a sealing structure of an organic electroluminescent display that can fully bond a sealing member to a substrate and does not degrade an organic electroluminescent element during manufacture. An organic electroluminescent element (12) is formed on a substrate (10), and the organic electroluminescent element (12) is formed by using a sealing member (14) composed of flat glass with an adhesive (16) composed of an ultraviolet curable resin. Bonded to the substrate (10) to be sealed. Dry nitrogen is encapsulated inside the sealed structure.

Description

technical field

[0001] The present invention relates to an improvement in the sealing structure of an organic electroluminescent display in which an organic electroluminescent element is formed on a substrate. Background technique

[0002] Conventionally, there have been proposed organic electroluminescent displays in which organic electroluminescent elements composed of thin film transistors, organic light-emitting layers, etc. are formed on a substrate. Since such organic electroluminescent elements are degraded by moisture, they cannot be exposed directly to the outside air. touch. For this reason, the organic electroluminescent element is usually sealed by a sealing member, and is isolated from the outside air.

[0003] image 3 A cross-sectional view showing an example of the sealing structure of the above-mentioned conventional organic electroluminescent display is shown. exist image 3 In the present invention, an organic electroluminescence element 12 is formed on ...
