Abstract: A liquid crystal display panel comprises a TFT substrate unit having a thin film transistor (TFT), a control electrode connected to the TFT, a flattening film covers the control electrode, and a pixel electrode having a cross slit and formed on the flattening film and insulated from the control electrode. An opposite substrate unit has an opposite electrode facing the pixel electrode at predetermined space. A liquid crystal layer disposed between the TFT substrate unit and the opposite substrate and includes liquid crystal molecules having negative dielectric aeolotropy. When voltage is supplied between the control electrode and the opposite electrode, an electric field is generated between them. The electric field divides the liquid crystal layer into four domains in each pixel according to the cross slit formed in the pixel electrode.

Abstract: A VA (Vertical Aligned) type active-matrix liquid crystal display capable of stabilizing a boundary position between divided areas (alignment areas). The liquid crystal display comprises a TFT (thin film transistor) substrate including a pixel electrode provided for each pixel and a driving element such as a TFT provided for each pixel electrode, an opposite substrate disposed opposite to the TFT substrate and including an opposite electrode, and a liquid crystal layer sandwiched between the TFT substrate and the opposite substrate. Each pixel electrode has a recess in groove shape formed therein. The pixel electrode preferably has a generally rectangular shape. The recess is provided such that it extends from one of a pair of opposite sides of the pixel electrode to the other to divide the pixel electrode into two parts.
