Patent ID: 8305538

Claim:
An active matrix vertical alignment liquid crystal display apparatus, comprising: transparent pixel electrodes, scan lines are formed on a thin film transistor (TFT) substrate; a transparent insulating film is formed on transparent pixel electrodes, and video signal lines and common lines are formed on the transparent insulating film; transparent pixel electrodes are electrically connected to drain electrodes of TFT; first liquid crystal alignment control electrodes and second liquid crystal alignment control electrodes are formed on the transparent insulating film, or are formed on a passivation film of TFT; the first liquid crystal alignment control electrodes and the second liquid crystal alignment control electrodes are slender and parallel with each other, and are positioned alternately; the first liquid crystal alignment control electrodes are electrically connected to a transparent pixel electrode; and the second liquid crystal alignment control electrodes are electrically connected to a common line in a pixel the transparent pixel electrodes are closer to the video signal lines and the common lines than the liquid crystal alignment control electrodes, and the first liquid crystal alignment control electrodes are closer to the video signal lines and the common lines than the second liquid crystal alignment control electrodes; the video signal lines are aligned in parallel with odd-numbered columns and even-numbered columns of common electrode, and a voltage is applied to signals with different opposite polarities within a horizontal scan period (H period); a transparent common electrode is positioned opposite to the TFT substrate, and is connected to common lines formed on the TFT substrate, and there are no slits in the transparent common electrode, and there are no bumps on the transparent common electrode.
