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.
