ABSTRACT:
A liquid crystal display system is provided with a driving circuit which corrects the display position in a vertical direction to obtain an excellent display area even when the total vertical line number is short. According to the driving circuit, by switching the output alternating signal GM input to a scan driver 701-1 in a scan driving circuit 104, a selection voltage Vgon is reflected to all the output terminals of the scan driver 701-1 to switch plural lines at the same time and perform a write-in operation. In a scan driver 701-2 and subsequent scan drivers in the scan driving circuit 104, an FLM signal is input to successively reflect the selection voltage Vgon to the output terminals thereof and successively select the line, thereby performing a write-in operation.
