Abstract
A display apparatus includes: a display panel including pixels respectively connected to gate lines and data lines; a data driving circuit to output a data output signal in response to a data signal; a demultiplexer circuit to provide first and second data lines from among the data lines with the data output signal, in response to control signals; and a driving controller to provide the data signal and the control signals. The demultiplexer circuit includes: a switching transistor including a first electrode to receive the data output signal, a second electrode connected to the first data line, and a gate electrode connected to a first node; and a switching control circuit to charge the first node to turn on the switching transistor during a first interval of a first horizontal period, and to discharge the first node during a second interval of the first horizontal period.
