Abstract

The present invention provides a transparent sealant for organic EL element, which is excellent in flexibility and can seal the organic EL element sufficiently, and thus can suppress generation of dark spots thereby capable of enhancing visibility of an image when an organic EL display is produced. The transparent sealant for organic EL element 2 of the present invention is formed with a flexiblepolymer composition, and is disposed between the light emitting face of a light emitting element 3 and the sealing member 4 in an electroluminescence display panel 1 comprising the light emitting element 3 sequentially including a substrate 31, an anode layer 32, a light emitting layer 33 and a cathode layer 34, and a sealing member 4 disposed on the light emitting side of the light emitting element 3.

Description

technical field

[0001] The present invention relates to a transparent sealing material for organic EL elements. More specifically, it relates to a transparent sealing material for organic EL elements for filling voids on the light-emitting surface side of light-emitting elements constituting an electroluminescence display (hereinafter referred to as "EL display"). The transparent sealing material for organic EL elements of the present invention is suitable for use in EL displays for mobile phones, portable information terminals, desktop computers, notebook computers, televisions, in-vehicle information devices, clocks, and other various display devices. technical background

[0002] Since the EL element emits light by itself, a display device including the EL element has high visibility. Utilizing this property, a high-performance display device having an organic EL element capable of lowering the applied voltage than an inorganic EL element, ie, an organic EL display, is b...
