    Abstract: A display device includes a display area configured to include a plurality of pixels and a plurality of data lines connected to the pixels. A hole area is disposed within the display area. A hole crack detection line is disposed adjacent to the hole area and surrounds the hole area. The device includes first and second detection lines which include first and second detection transfer lines and first and second detection receiving lines, respectively. A test controller electrically connects the first detection receiving line to a first data line and the second detection receiving line to a second data line. Pixels connected to the first data line that is connected to a first bright-line transistor and pixels connected to the second data line that is connected to a second bright-line transistor are configured to emit light when a crack occurs in the hole crack detection line.

    Abstract: A display device includes: a first pixel connected to a first data line and a first scan line; a second pixel connected to the first data line and a second scan line; a first scan driver connected to a first scan start line and the first scan line; and a second scan driver connected to a second scan start line and the second scan line. In a first frame period, the second scan start line is to be suppled with a second scan start signal having a turn-on level, after a first period elapses after a first scan start signal having a turn-on level is supplied to the first scan start line. In a second frame period, a difference between a time at which the first scan start signal having the turn-on level is supplied and a time at which the second scan start signal having the turn-on level is supplied corresponds to a second period. The second period is shorter than the first period.
