Title:
ORGANIC EL PANEL AND PROCESS FOR PRODUCING ORGANIC EL PANEL
Document Type and Number:
WIPO Patent Application WO/2010/001831
Kind Code:
A1
Abstract:
Disclosed is a solid sealing method that, in lamination through a sealing material, does not lead to such a defect that the sealing material is extended to contaminate an external electrode. Also disclosed is a solid sealing method that can cope with multiple face (multiple pieces) obtainment in the production of organic EL. The sealing method is used in a process for producing an organic EL panel, comprising laminating a sealing substrate through a sealing material onto a substrate, on which an organic EL element comprising at least a first electrode layer, an organic compound layer including a luminescent layer, and a second electrode layer has been formed, by face bonding to form an airtight sealing structure. The sealing method is characterized by comprising placing a liquid sealing material on at least one of the substrate and the sealing substrate, temporarily curing only the sealing material of the outer peripheral part of the substrate and the sealing substrate to a viscosity of 50 Pa∙sec to 5000 Pa∙sec, stacking the substrate onto the sealing substrate, and further curing the whole sealing face of the sealing material to form an airtight sealing structure.
