Abstract

The present invention prevents air bubbles from being mixed in at the time of resin filling. In a supplying step (FIGS. 5 D, 5 E), a transparent resin filler is dispensed and supplied from supply means so that the transparent resin filler comes into contact with both of an image display panel and a front panel to draw a predetermined pattern, and the transparent resin filler is maintained in contact with both of the panels until drawing of the predetermined pattern is completed.

First claim

The invention claimed is:

1. A method for manufacturing a display device, the method comprising:
inserting a dispensing nozzle between an image display panel and a front panel of the display device;
supplying a transparent resin filler from the dispensing nozzle to form a predetermined pattern such that the predetermined pattern contacts both the image display panel and the front panel;
pressing the image display panel or the front panel at a pressure greater than a normal pressure;
spreading the transparent resin filler to fill a gap between the panels by subjecting the resin filler to the normal pressure; and
forming a transparent resin filled layer by curing the transparent resin filler.

2. The method for manufacturing the display device according to claim 1 , wherein, when the predetermined gap ranges from 2.5 to 5.5 mm, a viscosity of the transparent resin filler ranges from 800 to 3500 mPa·s.

3. The method for manufacturing the display device according to claim 2 , wherein the transparent resin filler comprises a photoreactive acrylate material and a photopolymerization initiator.

4. The method for manufacturing the display device according to claim 3 , wherein the predetermined pattern comprises a central portion pattern that is positioned in a central portion of the image display panel or the front panel and a corner portion pattern that is positioned in a corner portion of the image display panel or the front panel.

5. The method for manufacturing the display device according to claim 4 , wherein the central portion pattern is a belt-like pattern that extends linearly and that intersects a second belt-like pattern.

6. The method for manufacturing the display device according to claim 1 , wherein, the pressing is performed until the transparent resin filled layer has a predetermined thickness.

7. The method for manufacturing the display device according to claim 1 , wherein the inserting inserts a plurality of dispensing nozzles from opposite sides of the image panel and the front panel, and wherein the panels are rectangular.

8. The method according to claim 1 , wherein the pressing fills an entirety of the gap.

9. The method according to claim 4 , wherein the central portion pattern contacts the corner portion pattern.

10. The method according to claim 4 , wherein the central portion pattern and the corner portion pattern are continuously drawn.

11. The method according to claim 4 , wherein the central portion pattern and the corner portion pattern are independently drawn.
