Filed: 1988-09-08
Abstract: PURPOSE:To dispense with the increment of a circuit for preventing flicker, etc., and a driver with specific constitution and to attain miniaturization and a low cost by arranging image elements of same color connected to a pair of scanning lines non-linearly in the extending direction of a signal line in a full-line liquid crystal color display device. CONSTITUTION:The same color of the image element connected to a drain line 1 is attached on every line of gate lines 2, 2. Therefore, two image elements can be driven with the same data. It is necessary to shift a sampling timing when it is expected to obtain accuracy in horizontal deviation, however, it is not worried about the deviation of one image element when an image is observed actually since the deviation is not caused due to switching of right and left image elements but relative deviation in the image elements. However, it is enough to shift the wiring of the image element by the half of image element to the gate line 2 to reduce the deviation as shown in figure 4.
