1. A display device comprising:
- a display panel in which pixel arrays include pixels that are disposed in a matrix form according to an intersection structure of data lines and gate lines, the pixel arrays divided into a main display unit and an auxiliary display unit both on a common substrate;
a data driver configured to supply a data voltage to the data lines;
a first gate driver connected to gate lines of the main display unit; and
a second gate driver connected to gate lines of the auxiliary display unit,wherein, in a full display mode, the first gate driver supplies first gate pulses to the gate lines of the main display unit and the second gate driver supplies second gate pulses to the gate lines of the auxiliary display unit, andin an always-on mode, the first gate driver fixes a voltage of the gate lines of the main display unit to a negative polarity voltage less than a ground voltage during an entire duration of the always-on mode, and the second gate driver supplies the second gate pulses to the gate lines of the auxiliary display unit.

Abstract
A display device and a mobile terminal include a main display unit and an auxiliary display unit that are driven in a full display mode or an always-on mode. The display device includes a data driver configured to supply a data voltage to the data lines, a first gate driver connected to gate lines of the main display unit, and a second gate driver connected to gate lines of the auxiliary display unit. In the full display mode, at least a portion of the main display unit and the auxiliary display unit display image data. In the always-on mode, at least a portion of the auxiliary display unit displays image data.
