Abstract

A display apparatus is disclosed, which comprises a demultiplexing circuit portion for sequentially supplying data signals supplied from a data driving circuit to at least two data lines, the demultiplexing circuit portion including a switching portion for sequentially supplying the data signals to at least two data lines based on a voltage of a control line, a voltage controller for controlling the voltage of the control line in response to a time-division control signal and an auxiliary signal partially overlapped with the time-division control signal, and a voltage discharge portion for discharging the voltage of the control line in response to the time-division control signal. Therefore, an off current capable of being transferred to an organic light emitting diode may be prevented from occurring, a bezel area may be minimized, and an image of high resolution of a display panel may be embodied.
