Embodiment Construction

[0050] Hereinafter, modes for implementing the present invention will be described, but the present invention is not limited to the embodiments described below at all, and the embodiments can be implemented by arbitrarily changing the embodiments within a range not departing from the gist of the present invention.

[0051] (Manufacturing method of organic EL panel)

[0052]The organic EL panel of the present embodiment is manufactured by the following method: forming a long element substrate of an organic EL element having a first electrode, an organic functional layer including a light-emitting layer, and a second electrode on the surface; A long sealing substrate having an adhesive layer made of curable resin is bonded to the surface of the element substrate on which the organic EL element is formed and the surface of the sealing substrate on which the adhesive layer is formed to form a sealed structure.

Abstract

Provided are: a production method for an organic electroluminescent panel that enables continuous production using elongated base materials, prevents positional shifts and peeling after the elongated base materials have been bonded, and prevents an increase in the scale of the production apparatus; and a production method for the organic electroluminescent panel. The production method for the organic electroluminescent panel is characterized by comprising: a bonding step in which a multilayer substrate is formed by bonding an elongated element substrate obtained by forming organic electroluminescent elements on a surface, and an elongated encapsulation substrate obtained by forming an adhesion layer composed of a curable resin on a surface; a linear conveyance step in which the multilayer substrate is conveyed in a linear fashion; a first curing step in which the adhesion layer is cured while conveying the multilayer substrate in a linear fashion; and a second curing step in which the adhesion layer is cured while conveying the multilayer substrate in a bent fashion. The production method for the organic electroluminescent panel is further characterized in that the abovementioned steps are performed in the abovementioned order.

Description

technical field [0001] The present invention relates to a method and device for manufacturing an organic electroluminescent panel (hereinafter also referred to as "organic EL panel"), and an organic EL panel manufactured by the method and device. Background technique [0002] If the material and the light-emitting unit constituting the light-emitting layer of the organic EL panel absorb moisture, the light-emitting brightness will be significantly impaired. Therefore, it is necessary to keep the inside of the organic EL panel in a low-humidity environment, and provide a member for shielding and protecting it from exposure to the outside air to form a sealed structure. [0003] As a method of manufacturing an organic EL panel, there is disclosed a housing type method in which, for example, a glass cover or a metal can and an adhesive material are used to make an airtight space and an organic electroluminescent element (hereinafter also referred to as "organic EL") is placed t...
