Abstract
A driver circuit drives display device and LCD device has a driver circuit that includes driving stages and dummy stage. The driving stage includes output and control terminals. The output terminal of the present stage is connected to the control terminal of the previous state to be cascade-connected each other. The driving stage outputs driving signal for controlling the switching device arranged on the display device through the output terminal. The dummy stage includes dummy output terminal and dummy control terminal. The dummy output terminal is connected to the control terminal of the last driving stage to output dummy output signal for turning on or off the last driving stage. The dummy control terminal is connected to the dummy output terminal to be turned on or off by the dummy output signal. The delay of signals is reduced, thereby enhancing display quality.
