1. A method for manufacturing a display device, comprising:
preparing a substrate to be processed, the substrate to be processed including:
a display area of the display device at which an image is displayed defined therein,
a non-display area at which the image is not displayed defined therein,
a first substrate of the display device,
a first alignment layer of the display device which is on the first substrate, wherein the first alignment layer is disposed in the display area and the non-display area; and
an overcoat layer of the display device which is disposed between the first substrate and the first alignment layer, the overcoat layer disposed in the display area and the non-display area;
irradiating ultraviolet rays to the substrate to be processed including the first alignment layer and the overcoat layer which is exposed from the first alignment layer in the non-display area, by using a mask having a transmitting portion which transmits the ultraviolet rays to the first alignment layer of the substrate to be processed and a blocking portion which blocks transmission of the ultraviolet rays to the overcoat layer in the non-display area of the substrate to be processed; and
bonding an opposed substrate which faces the substrate to be processed to the substrate to be processed.
