Abstract
To prevent bubbles from remaining when a transparent substrate is bonded via an adhesive with a display panel. A manufacturing method of a display device in which a transparent substrate is bonded with a display panel via an adhesive, including a coating step of coating the adhesive onto the display panel or the transparent substrate in a predetermined pattern, a bonding step of bonding the display panel and the transparent substrate via the adhesive after the coating step, and a curing step of curing the adhesive after the bonding step, characterized in that the adhesive has a viscosity of 2000 to 5000 mPa·s at the coating step, the display panel and the transparent substrate are bonded via the adhesive in a reduced pressure atmosphere lower than the atmospheric pressure in a state where the adhesive coated at the coating step is spread and the size of bubble is 1 mm or less at maximum at the bonding step, and the adhesive is cured by applying ultraviolet ray at the curing step.
