Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. 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, wherein the first marker and the second marker each include a plurality of lines and a space provided between the plurality of lines, and in at least either the first marker or the second marker, one of the plurality of lines has a width different from a width of another line of the plurality of lines. 2. The display device according to claim 1 , wherein the first marker and the second marker are provided in each of the four corner areas of the substrate. 3. The display device according to claim 2 , wherein at least either the first markers or the second markers have different shapes in the four corner areas of the substrate. 4. The display device according to claim 1 , further comprising: a third marker located in an area that is along the longer side and is in each of the four corner areas of the substrate; and a fourth marker located an area that is along the shorter side and is in each of the four corner areas of the substrate. 5. The display device according to claim 1 , wherein the first marker and the second marker are located in a layer including any of lines included in the display portion. 6. The display device according to claim 1 , wherein the substrate is a flexible substrate. 7. The display device according to claim 1 , wherein the pixels each include an organic EL element.
