A display manufacturing device sticks a transparent panel to a display panel, the display panel including a front surface having a periphery covered by a bezel. The display manufacturing device includes: 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. 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 between the front surface and the bezel.
