Abstract
The present invention provides a patterned vertical alignment (PVA) pixel electrode comprising: a first electrode in the form of a “” or “” shape disposed on a TFT array substrate; and a second electrode in the form of a “” or “” shape corresponding to the first electrode and disposed on a CF substrate, wherein the first electrode and/or the second electrode includes ITO slits with unequal length which are disposed between the fringes of the first electrode and the second electrode for improving a display quality of the pixel. The present invention further provides a liquid crystal display (LCD) apparatus. The PVA pixel electrode and the LCD apparatus using the same can raise a transmittance and a display quality of the pixel.
