    Abstract: A display device may include a first scan line, a first data line and a second data line, a first read-out line and a second read-out line. A first sub-pixel may be connected to the first scan line, the first data line, and the first read-out line. A second sub-pixel may be connected to the first scan line, the first data line, and the second read-out line. A third sub-pixel may be connected to the first scan line, the second data line, and the first read-out line. Each of the first sub-pixel, the second sub-pixel, and the third sub-pixel may include at least one light emitting element.
