Abstract:
A liquid crystal display apparatus comprising:a pair of substrates, at least one of which is transparent; a liquid crystal layer interposed between said pair of substrates; a plurality of first scanning lines and a plurality of signal lines formed so as to cross each other in a matrix form; a plurality of first active elements, each formed proximate to a crossing point of a corresponding signal line and a corresponding first scanning line, pixel electrodes connected to said first active elements, common lines arranged in parallel with said first scanning lines, and common electrodes connected to said common lines, are arranged on one of said pair of substrates, and a liquid crystal display is provided in the liquid crystal layer by a voltage applied to said pixel electrodes and common electrodes; and a plurality of second active elements connected to said common electrodes, said pixel electrodes corresponding to the common electrodes, and second scanning lines different from said first scanning lines connected through said first active elements to said pixel electrodes, wherein a selection pulse to write an image signal in said pixel electrodes and a selection pulse to display the following image are applied, via one of the first and second scanning lines, and a clear pulse to clear the image signal applied to said pixel electrodes is applied, via the common lines.
