<p>PURPOSE:To provide a liquid crystal display device which is free from malfunctions and is capable of making high-speed operation by eliminating the phase difference by deviation in timing of a clock CL and antiphase clock CL* of the liquid crystal display device of an active matrix system. CONSTITUTION:There are two methods as the method for decreasing the phase differences of the clock. First is a method for connecting such a circuit (pulse correction circuit 1914) which prevents a clock signal and antiphase clock signal from simultaneously turning to an 'H' or 'L' between a clock signal line and an antiphase clock signal line. Second is a method for incorporating an antiphase clock signal generating circuit onto the same substrate. These two circuits are disposed just before a shift register for a higher effect. Then, the disposition of these circuits for each of respective bits may be said to be the most ideal method. A further higher effect is obtd. if the pulse correction circuit 1914 and the antiphase clock signal generating circuit are combined.</p> |
