Electroluminescent display having an adhesive layer comprised of two or more liquids
View Patent ↗Provided is a display apparatus which can easily bond a drive panel ( 10 ) and a sealing panel ( 20 ) together. The drive panel ( 10 ) includes organic electroluminescence devices ( 10 R), ( 10 G) and ( 10 B) on a substrate for drive ( 11 ) and extracts light from the side of the organic electroluminescence devices ( 10 R), ( 10 G) and ( 10 B). The sealing panel ( 20 ) includes a color filter ( 22 ) on a substrate for sealing ( 21 ). The drive panel ( 10 ) and the sealing panel ( 20 ) are disposed to face each other, and the whole facing surfaces of the drive panel ( 10 ) and the sealing panel ( 20 ) are bonded together with an adhesive layer ( 30 ). The adhesive layer ( 30 ) is cured with at least heat, and is made of only one coating liquid or a combination of two or more coating liquids for curing. A temporary fixing portion ( 30 A) is formed in an edge portion of the adhesive layer ( 30 ). The temporary fixing portion ( 30 A) is made of, for example, an ultraviolet cure resin, and is formed so as to straddle between the sealing panel ( 20 ) and the drive panel to align their relative positions.
1. A display apparatus, comprising:
a drive panel including a plurality of organic electroluminescence devices with a first electrode, one or more organic layers including a light-emitting layer, and a second electrode laminated an a substrate, wherein light generated in the light-emitting layer is emitted from the side of the second electrode;
a sealing panel for sealing, and facing the drive panel on the side of the second electrode;
an adhesive layer disposed between the sealing panel and the drive panel so as to cover the plurality of organic electroluminescence devices, and
a temporary fixing portion for fixing the relative positions of the sealing panel and the drive panel before the adhesive layer is cured, located exclusively along an edge portion of the adhesive layer immediately adjacent thereto and connecting a side surface portion of the sealing panel and a portion of the drive panel: and further wherein the adhesive layer is made of a combination of two or more coating liquids for curing and the combination of two or more coating liquids is mixed through coating at substantially the same time.
