The first minimum distance is the minimum distance in a direction from the display area to a non-display area and between the boundary of the display area and the boundary of the functional layer, and is determined by a first shadow width of the functional layer extending from the display area to the non-display area. The first shadow width is the maximum width of a shadow area formed within a preset region when the functional layer is vapor deposited in the preset region.
