  • Publication number: 20150360455
    Abstract: The present invention provides a method of applying a photocurable resin on a surface of a panel. A difference in a surface level is formed on a peripheral portion on the surface of the panel. The method includes a step of moving either one of an application head and the panel so that the application head provided with a slit-type nozzle which discharges a photocurable resin relatively moves on the surface of the panel, and an application step of discharging the resin from the nozzle onto the surface of the panel during the moving step. In the application process, a film thickness of the resin is controlled so that a difference in a surface level is not generated on a liquid film surface of the resin on the difference in a surface level on the panel.
