Transparent display device reducing number of pixel driving lines

A display device comprising:

• a unit pixel group including a plurality of pixels;
• a data driver that supplies a data signal to the unit pixel group through a data line;
• a gate driver that supplies a first scan signal to a third scan signal to the unit pixel group through a first gate line to a third gate line;
• and
• a power supply unit that supplies a first power voltage to a third power voltage to the unit pixel group through a first power line to a third power line,
• wherein the unit pixel group includes:
• a first pixel to a third pixel that are sequentially disposed on a first column parallel to a first direction along the first direction;
• a fourth pixel to a sixth pixel that are sequentially disposed on a second column that is adjacent to the first column in a second direction that is different from the first direction, along the first direction;
• a seventh pixel to a ninth pixel that are sequentially disposed on a third column that is adjacent to the second column in the second direction, along the first direction;
• a first switching transistor including a gate electrode connected to the first gate line, a first electrode connected to the data line, and a second electrode commonly connected to the first pixel, the fourth pixel, and the seventh pixel;
• a second switching transistor including a gate electrode connected to the second gate line, a first electrode connected to the data line, and a second electrode commonly connected to the second pixel, the fifth pixel, and the eighth pixel;
• and
• a third switching transistor including a gate electrode connected to the third gate line, a first electrode connected to the data line, and a second electrode commonly connected to the third pixel, the sixth pixel, and the ninth pixel, and
• wherein one frame includes:
• a first sub frame in which the first pixel to the third pixel emit light;
• a second sub frame in which the fourth pixel to the sixth pixel emit light;
• and
• a third sub frame in which the seventh pixel to the ninth pixel emit light.
