A method includes preparing a substrate including a display area and a non-display area disposed adjacent to the display area, forming first panel magnetic patterns overlapping the non-display area and extending in a first direction on the substrate, forming first film magnetic patterns extending in the first direction on a film, inputting a first magnetism to the first panel magnetic patterns so that the first panel magnetic patterns have a first magnetic property, inputting a second magnetism to the first film magnetic patterns so that the first film magnetic patterns have a second magnetic property, and aligning the film on the substrate so that the first film magnetic patterns overlap the first panel magnetic patterns in a plan view.
