Abstract
In a display device, a defective subpixel has one region being a non light-emitting region conforming to the planar shape of conductive foreign matter and the other region being a light-emitting region. The display device includes a cathode electrode provided commonly to a plurality of red pixels, green pixels, and blue pixels. In the defective subpixel, the cathode electrode has a light emission corresponding portion and a non light emission corresponding portion that are not electrically connected with each other.

1-4. (canceled)
A display device comprising:
- a plurality of subpixels configured to emit light of mutually different colors,
- wherein the plurality of subpixels include at least one defective subpixel containing foreign matter,
- the at least one defective subpixel includes
- one region including a non light-emitting region conforming to a planar shape of the foreign matter, and
- the other region including a light-emitting region,
- each of the plurality of subpixels includes
- a substrate, and
- a first electrode, a light-emitting layer, and a second electrode in this order on the substrate,
- the second electrode is provided commonly to the plurality of subpixels,
- in the at least one defective subpixel, a portion, corresponding to the light-emitting region, of the second electrode is not electrically connected with a portion, corresponding to the non light-emitting region, of the second electrode,
- in a pixel including the at least one defective subpixel, a normal subpixel containing no foreign matter includes one region including a non light-emitting region and the other region including a light-emitting region, and
- the light-emitting regions of the at least one defective subpixel and the normal subpixel are configured to emit light of mutually different colors.
9-16. (canceled)
A defect correction apparatus configured to correct a defect occurring in at least any one of a plurality of subpixels included in a display device, the plurality of subpixels being configured to emit light of mutually different colors, the defect correction apparatus comprising:
- a laser light radiation unit configured to radiate laser light along an outer periphery of a region containing foreign matter in the at least any one of the plurality of subpixels containing the foreign matter in conformance to a shape of the foreign matter contained in the at least any one of the plurality of subpixels, without using a prescribed pattern determined preliminarily,
- wherein the laser light radiation unit is configured to form a non light-emitting region and a light-emitting region in each of a defective subpixel and a normal subpixel of a pixel including the defective subpixel by radiating the laser light toward a partial region of the normal subpixel, the defective subpixel including a subpixel containing the foreign matter, the normal subpixel including a subpixel containing no foreign matter, and
- the light-emitting regions of the defective subpixel and the normal subpixel are configured to emit light of mutually different colors.
