Problems solved by technology

[0017] However, if the moisture absorbing agent is placed in the concave portion of the entire sealing plate facing the EL laminate, the second problem that arises is that the top emission structure that obtains light from the light-emitting layer from the side of the sealing plate cannot Obtain a sufficient aperture ratio, so that the light from the light-emitting layer cannot be sufficiently obtained

Embodiment 1

[0123] In Example 1, the thickness of the adhesive layer was uniform over the entire area of ​​the sealing portion between the substrate and the peripheral protrusion, and the half-reduced life of luminance was 5000 hours, showing a very high life.

[0124] In addition, the initial driving voltage is 8V. As the driving time increases, the brightness decreases. In order to maintain the brightness, the driving voltage needs to be increased. However, as long as the initial driving voltage is increased to 12V, the brightness can be maintained.

Abstract

A sealing plate for an EL device, which effectively prevents water or oxygen from entering the EL device, thereby prolonging the life of the EL device; a sealing plate for a top emission EL device, which can suppress deterioration of a mother glass substrate for a multi-production of the sealing plate and that of an EL multilayer film while sufficiently taking out the light from a light-emitting layer; a method for manufacturing such a sealing plate; and a mother glass substrate for a multi-production of the sealing plate are provided. The EL device (100) comprises a transparent substrate having a planar shape, an organic EL stacked body and a sealing plate (30). The sealing plate (30) has a recess in the central portion, thereby providing a peripheral projection part (31) on the periphery, and the height of the roughness of the top surface of the peripheral projection part (31) is less than 10mum at the maximum.

Description

technical field [0001] The invention relates to a sealing plate for an electroluminescent element, a manufacturing method thereof, and a sample glass substrate for producing a plurality of the sealing plates. Background technique [0002] An electroluminescent (hereinafter referred to as EL) element is generally composed of a substrate formed on the surface and a sealing plate for an EL element whose central part is processed into a concave shape so as to define a peripheral convex in a peripheral part. The raised portion, the top surface of the peripheral raised portion is bonded to a substrate by an adhesive, and is used to cover the EL laminated film formed on the substrate. The substrate and the sealing plate are bonded together by an adhesive layer formed of an adhesive disposed on the sealing portion between the substrate and the peripheral raised portion. [0003] As a material of the sealing plate, metal, glass, resin, or the like can be used. Among them, when the ...
