The first switching element applies first pixel data to a first pixel connected with a first data line of a display panel during a first sub frame period. The first switching element is connected with a data channel of a data driving part. The second switching element applies second pixel data having a level higher than a level of the first pixel data to a second pixel connected with a second data line of the display panel during a second sub frame period. The second switching element is connected with the data channel. Thus, display quality of a display apparatus may be enhanced.
