Abstract
A display device includes a substrate; a display portion located on the substrate, the display portion including a plurality of pixels; a first marker located in an end area that is along a longer side of the substrate and is in at least one of four corner areas of the substrate, the first marker extending in a longer axis direction of the substrate; and a second marker located in an end area that is along a shorter side of the substrate and is in the same corner area as that of the first marker, the second marker extending in a shorter axis direction of the substrate.
Claims11
A display device, comprising:
- a substrate;
- a display portion located on the substrate, the display portion including a plurality of pixels;
- a first marker located in an end area that is along a longer side of the substrate and is in at least one of four corner areas of the substrate, the first marker extending in a longer axis direction of the substrate;
- and
- a second marker located in an end area that is along a shorter side of the substrate and is in the same corner area as that of the first marker, the second marker extending in a shorter axis direction of the substrate.
A method for manufacturing a display device, the method comprising:
- forming a substrate on a support member;
- forming a display portion and a peripheral portion on the substrate;
- forming a first marker in a first corner area of one side of the substrate;
- forming a second marker in a second corner area of the one side of the substrate;
- acquiring a first central line of the first marker;
- acquiring a first central line of the second marker;
- peeling off the support member from the substrate;
- acquiring a second central line of the first marker;
- acquiring a second central line of the second marker;
- acquiring a first cutting line based on a first difference between the first central line of the first marker and the second central line of the first marker;
- acquiring a second cutting line based on a second difference between the first central line of the second marker and the second central line of the second marker;
- and
- cutting the substrate based on the first cutting line and the second cutting line.
