Organic el panel, panel-combined light emitting device, and method of manufacturing organic el panel

A panel-combined light-emitting device having a plurality of organic EL panels planarly jointed to each other to make a large-sized panel, the organic EL panel comprising:

• a panel substrate and a light-emitting part including a plurality of organic EL elements having an anode, an organic layer and a cathode laminated on the panel substrate;
• and
• a sealing substrate configured to be bonded onto the panel substrate through an adhesive layer to hollow-seal the light-emitting part, wherein
• the sealing substrate includes a supporting projection projecting toward the panel substrate,
• a supporting margin facing a bottom face of the supporting projection is provided where the organic EL elements are not formed within a region of the light-emitting part on the panel substrate,
• the light-emitting part is configured with a plurality of pixel blocks, each of which has a plurality of organic EL elements, while the supporting margin is configured between the pixel blocks, and
• the distance between the pixel blocks is defined in accordance with the distance between the adjacent light-emitting parts of the organic EL panels.

A method of manufacturing an organic EL panel comprising:

• forming a light-emitting part having at least one organic EL element on a panel substrate;
• forming a concave portion for housing the light-emitting part on a sealing substrate;
• and
• sealing the light-emitting part by bonding the panel substrate and the sealing substrate together through an adhesive layer, wherein
• a supporting projection projecting toward the panel substrate is formed while the concave portion is being formed, and
• a supporting margin facing the bottom face of the supporting projection is provided where the organic EL elements are not formed within a region of the light-emitting part on the panel substrate.
