Display device and method of driving the same

A display device comprising:

• a first display area including first pixels and first data lines connected to the first pixels;
• a second display area including second pixels and second data lines connected to the second pixels, the second display area being adjacent to the first display area in a horizontal direction and having a length less than a length of the first display area in a vertical direction;
• a first non-display area being adjacent to the first display area and the second display area in the horizontal direction and the vertical direction, respectively;
• a data driver configured to output data signals corresponding to the first and second pixels through first and second output lines, respectively;
• and
• a switch unit connected between the first and second output lines and the first and second data lines, the switch unit comprising:
• a first switch unit comprising a demultiplexer configured to alternately connect each of the first output lines to a plurality of corresponding first data lines;
• and
• a second switch unit configured to connect the second output lines to different second data lines, respectively,
• wherein the first data lines and the second data lines extend in the vertical direction in the first display area and the second display area, respectively, and
• wherein the second data lines extend from the second display area, through the first non-display area, to the second switch unit, and the second data lines are arranged at a first interval in the second display area and at a second interval less than the first interval in the first non-display area.
