A purpose of the present invention is to provide a display apparatus which can improve driving efficiency. The display apparatus comprises: a latch unit for distributing inputted first data into second data having a data quantity larger than the first data, and outputting the second data; a digital-analog conversion unit for converting the second data into gray scale indicating voltages; an output buffer unit for generating data voltages by amplifying the gray scale indicating voltages with current; a data switching unit for inverting a polarity of the data voltages for each frame, and outputting the data voltages; and a display panel including a plurality of pixels operated by receiving the data voltages through the data switching unit in response to sequential gate signals.
