1. A display device comprising:
a plurality of scanning signal lines;
a plurality of data signal lines; and
a plurality of subpixel circuits disposed at least at one or more intersection points of the plurality of scanning signal lines and the plurality of data signal lines, each of the plurality of subpixel circuits including a control circuit having a transistor and a light-emitting element,
wherein an average density of the plurality of subpixel circuits provided in a display region, which is a number of the plurality of subpixel circuits provided in the display region over an area of the display region, is greater than an average density of the plurality of subpixel circuits provided in a sparse pixel region, which is another number of the plurality of subpixel circuits provided in the sparse pixel region over an area of the sparse pixel region,
the sparse pixel region includes a no-pixel region not including any of the plurality of subpixel circuits in one entire line in an extending direction of the plurality of scanning signal lines in the display region or an extending direction of the plurality of data signal lines provided in the display region,
a first data signal line corresponding to one of the plurality of data signal lines provided in the display region is formed also in the sparse pixel region in the extending direction of the plurality of data signal lines provided in the display region,
a second data signal line corresponding to another one of the plurality of data signal lines provided in the display region and provided most adjacent to the first data signal line is formed in the sparse pixel region also in the extending direction of the plurality of data signal lines provided in the display region,
a first sparse region subpixel circuit of the plurality of subpixel circuits provided in the sparse pixel region is electrically connected to the first data signal line,
a second sparse region subpixel circuit of the plurality of subpixel circuits provided in the sparse pixel region is electrically connected to the second data signal line,
a first display region subpixel circuit of the plurality of subpixel circuits provided in the display region is electrically connected to the first data signal line,
a second display region subpixel circuit of the plurality of subpixel circuits provided in the display region is electrically connected to the second data signal line, and
a distance between a portion of the first data signal line, laid in the first sparse region subpixel circuit, and a portion of the second data signal line, laid in the second sparse region subpixel circuit that is most adjacent to the first sparse region subpixel circuit, is shorter than a distance between a portion of the first data signal line, laid in the first display region subpixel circuit, and a portion of the second data signal line, laid in the second display region subpixel circuit that is most adjacent to the first display region subpixel circuit.
