Abstract
A liquid crystal display apparatus includes: a plurality of pixels arranged in a matrix, each including a switching element connected to a pixel electrode for applying a voltage to a liquid crystal placed between the pixel electrode and a counter electrode; and a vertical scan circuit for supplying a scan signal for controlling the switch element between conducting and non-conducting states, and for scanning the pixels scan line by scan line sequentially, wherein the scan signal includes a first conducting signal setting the switch element at the conducting state, a second conducting signal setting the switch element at the conducting state following to the first conducting signal, and a non-conducting signal setting the switch element at the non-conducting state between the first and second conducting signals to suppress deterioration of the image quality owing to the parasitic capacitance coupling between pixel electrodes and a feedthrough between pixels.
