A display manufacturing device for sticking a transparent panel to a display panel , the display panel including a front surface having a periphery covered by a bezel , wherein an inner peripheral edge of the bezel has a rectangular shape, the display manufacturing device comprising: a dispenser that makes a dam by dispensing a light curable resin to straddle the front surface of the display panel and the bezel , and be along an inner peripheral edge of the bezel to stick the transparent panel to the front surface of the display panel ; and at least one light irradiation device that emits light that cures the dam , wherein the at least one light irradiation device emits the light in a direction that forms an acute angle between the direction and the front surface of the display panel , the direction being a direction that allows the light to reach the light curable resin that has entered a gap (G) between the front surface and the bezel , wherein the display manufacturing device further comprises a movable head to which the dispenser is attached and that moves relative to the display panel in such a manner that the movable head moves parallel to the front surface of the display panel , and moves along an inner peripheral edge of the bezel , characterized in that the at least one light irradiation device includes two light irradiation devices that are attached to the movable head , and the movable head is configured to turn 90° about a turning center line (C) that passes through a center of a resin dispensing outlet of the dispenser and is perpendicular to the front surface of the display panel , and the two light irradiation devices are attached to the movable head in such a manner that the two light irradiation devices have a 180° rotational symmetry about the turning center line (C) of the movable head . a dispenser that makes a dam by dispensing a light curable resin to straddle the front surface of the display panel and the bezel , and be along an inner peripheral edge of the bezel to stick the transparent panel to the front surface of the display panel ; and at least one light irradiation device that emits light that cures the dam , wherein the at least one light irradiation device emits the light in a direction that forms an acute angle between the direction and the front surface of the display panel , the direction being a direction that allows the light to reach the light curable resin that has entered a gap (G) between the front surface and the bezel , wherein the display manufacturing device further comprises a movable head to which the dispenser is attached and that moves relative to the display panel in such a manner that the movable head moves parallel to the front surface of the display panel , and moves along an inner peripheral edge of the bezel , characterized in that the at least one light irradiation device includes two light irradiation devices that are attached to the movable head , and the movable head is configured to turn 90° about a turning center line (C) that passes through a center of a resin dispensing outlet of the dispenser and is perpendicular to the front surface of the display panel , and the two light irradiation devices are attached to the movable head in such a manner that the two light irradiation devices have a 180° rotational symmetry about the turning center line (C) of the movable head . <EOS>
