• a first substrate comprising a plurality of pixels, a plurality of gate lines configured to turn on the pixels in at least one row unit, and a plurality of data lines configured to apply a data signal to the turned on pixels;
• and
• a second substrate comprising a plurality of sensors, a plurality of scan lines configured to turn on the sensors in at least one row unit, and a plurality of readout lines configured to read out a signal from the turned on sensors, and
• wherein each of the readout lines is disposed between two of the data lines being adjacent to each other, and is disposed at a position closer to a center line between the two of the data lines than to the two of the data lines, wherein the two of the data lines are divided by the center line.
