b the scanning line driver 28 b impresses a scanning line drive voltage to the red liquid crystal layer 39 s scanning line below the fourth line of the blue liquid crystal layer b three scanning line shift clock pulses are then supplied to the scanning line drivers 28 a and 28 b respectively from the controller 32 followed by a scanning line latch signal consequently the scanning line driver 28 a impresses a scanning line drive voltage to the fifth scanning line electrode of the blue liquid crystal layer b as well as to the green liquid crystal layer 39 s scanning line below the sixth line of the blue liquid crystal layer b the scanning line driver 28 b impresses a scanning line drive voltage to the red liquid crystal layer 39 s scanning line below the seventh line of the blue liquid crystal layer b three scanning line shift clock pulses are then supplied to the scanning line drivers 28 a and 28 b respectively from the controller 32 followed by a scanning line latch signal consequently the scanning line driver 28 a impresses a scanning line drive voltage to the eighth scanning line electrode of the blue liquid crystal layer b as well as to the green liquid crystal layer 39 s scanning line below the ninth line of the blue liquid crystal layer b the scanning line driver 28 b impresses a scanning line drive voltage to the red liquid crystal layer 39 s scanning line below the tenth line which is a virtual.
