An optical film is shaped so that a first normal drawn from a starting point of a curve to an outer periphery of an application region is longer than a second normal drawn from the starting point of the curve to an outer periphery of a display region, a third normal drawn from an end point of the curve to the outer periphery of the application region is longer than a fourth normal drawn from the end point of the curve to the outer periphery of the display region, and a fifth normal drawn from a single point on the curve located between the starting point and the end point of the curve to the outer periphery of the application region is shorter than each of the first normal and the third normal.
