Abstract:
A liquid crystal display device including an active matrix array made up of switching elements provided at each intersection between a plurality of scanning lines and a plurality of signal lines, and driving means for driving said active matrix array, said driving means comprising:scanning circuits N in number, N being a positive integer, which receive a start pulse, and which produce pulse signals sequentially shifted by one-half of a clock signal cycle for each scanning circuit; first logic gate circuits NÃ—M in number, M being an integer no less than 2, each provided with a first control terminal and a second control terminal, every M adjacent first logic gate circuits being connected together via said first control terminals thereof, which receive a signal produced by one of said N scanning circuits, and every Mth first logic gate circuit being connected together via said second control terminal thereof, which receive one of M kinds of second control signal; and second logic gate circuits, each of which receives an output from one of said first logic gate circuits and, via a third control terminal, one of two kinds of third control signal.
