Claim:
1. A display apparatus comprising: a display panel comprising: a data driver configured to output a first data voltage and a second data voltage to the data lines and which controls a ratio between the number of the data lines which receives the first data voltage and the number of the data lines which receive the second data voltage; and an inversion compensating part configured to output an inversion compensating signal to control a ratio between the number of the data lines which receive the first data voltage and the number of the data lines which receive the second data voltage, wherein the first data voltage has a positive polarity during a first frame and a negative polarity during a second frame, the second data voltage has the negative polarity during the first frame and the positive polarity during the second frame, and wherein the data driver outputs alternately the first data voltage and the second data voltage to the data lines, and controls the number of the data lines which receive the first data voltage and the number of the data lines which receive the second data voltage based on the inversion compensating signal.
