1. A display device comprising:
a timing controlling part generating an image data, a data control signal and a gate control signal;
a data driving part generating a data voltage using the image data and the data control signal, and comprising a plurality of latches receiving and outputting the image data, a plurality of first source switches and a plurality of second source switches sequentially transmit the image data outputted from the plurality of latches, and a plurality of digital analog converters converting the image data transmitted through the plurality of first source switches and the plurality of second source switches into the data voltage and sequentially outputting the data voltage;
a gate driving part generating a gate voltage by using the gate control signal;
a display panel including a plurality of subpixels and displaying an image by using the data voltage and the gate voltage; and
a plurality of first MUX switches and a plurality of second MUX switches sequentially transmitting the data voltage to two of a same color among the plurality of subpixels,
wherein the image data includes first red to sixth red image data, first green to sixth green image data and first blue to sixth blue image data,
wherein the plurality of latches comprises:
a first latch receiving and sequentially outputting the first red, third red and fifth red image data;
a second latch receiving and sequentially outputting the second red, fourth red and sixth red image data;
a third latch receiving and sequentially outputting the first green, third green and fifth green image data;
a fourth latch receiving and sequentially outputting the second green, fourth green and sixth green image data;
a fifth latch receiving and sequentially outputting the first blue, third blue and fifth blue image data; and
a sixth latch receiving and sequentially outputting the second blue, fourth blue and sixth blue image data.
