Abstract
An active matrix type liquid crystal display which has storage capacitance cells formed on scanning lines, and which is designed to increase the aperture ratio. The pitch between each of adjacent pair of signal lines on a thin-film transistor array substrate is increased relative to the pitch between each of adjacent pair of scanning lines to form an oblong dot, different from those in displays constructed in the conventional manner. A portion of a pixel electrode is extended over a portion of the preceding-stage scanning line. The portions of the pixel electrode and the scanning line form a storage capacitance cell. Even if the display is designed so that the capacitance value of the storage capacitance cell is equal to that in the conventional displays, the light stop area can be reduced relative to that in the conventional displays, thereby increasing the aperture ratio.
