Abstract
The structure of pixel electrode constituting a pixel element of a liquid-crystal display device employing the capacitively coupling driving method and driving method for the device are described. The field of view angle at the main viewing direction is increased and the grayscale graduation reversal is eliminated through a procedure of sequentially increasing or decreasing, at each scanning busline, the value of compensating potential at a time when a potential being applied to the gate terminal of the switching element shifts from ON potential to OFF potential, to be applied on an adjacent scanning busline to which the storage capacitance is formed, by setting each of the values of storage capacitance ratio and parasitic capacitance ratio different through making each of the values of storage capacitance and parasitic capacitance formed between the plural pixel electrodes and respective switching elements within one pixel element different to each other.
