Display apparatus comprising temporary fixing portion adjacent an adhesive layer
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 on a substrate, wherein light generated in the light-emitting layer is emitted from the side of the second electrode;
a sealing panel with a color filter disposed on a substrate 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, the adhesive layer being comprised of a thermosetting material, 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 and connecting an end portions of the sealing panel and the drive panel, the temporary fixing portion being comprised of an ultraviolet curing material, and wherein
the adhesive layer is made of only one coating liquid or a combination of two or more coating liquids for curing, and
the combination of two or more coating liquids is mixed through coating at the same time.
2. 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 on a substrate, wherein light generated in the light-emitting layer is emitted from the side of the second electrode;
a sealing panel with a color filter disposed on a substrate 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, the adhesive layer being comprised of a thermosetting material, 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 and connecting an end portions of the sealing panel and the drive panel, the temporary fixing portion being comprised of an ultraviolet curing material, and wherein
the adhesive layer is made of only one coating liquid or a combination of two or more coating liquids for curing, and
the combination of two or more coating liquids is mixed through separately coating the coating liquids in order, then applying a pressure thereto.
3. A method for manufacturing a display device comprising the steps of:
forming a drive panel including a substrate and a plurality of organic electroluminescence devices on the substrate, each organic electroluminescence device having a first electrode, one or more organic layers including a light-emitting layer, and a second electrode;
forming a sealing panel including a color filter;
providing an adhesive comprised of a thermosetting material over the drive panel so as to cover the plurality of organic electroluminescence devices;
disposing the sealing panel so as to face the drive panel with the adhesive portion there between;
aligning the relative position of the sealing panel and the drive panel;
providing a temporary fixing portion of ultraviolet curing material along an edge portion of the adhesive portion;
curing the temporary fixing portion by applying ultraviolet rays before curing the adhesive portion; and
curing the adhesive portion by applying beat.
4. The method according to claim 3 , wherein the temporary fixing portion is cured by applying ultraviolet rays from the side of the sealing panel.
