An active matrix type liquid crystal display is disclosed. The liquid crystal display comprises a plurality of pixel elements arranged in the form of a matrix. Each of the pixel elements comprises a liquid crystal element, a dynamic memory cell and a switch device. The dynamic memory cell is disposed at the intersection point of a source line and a gate line to periodically perform refreshing for inversing the output status of the dynamic memory cell, wherein the transmittance of the liquid crystal element is controlled by a digital output of the dynamic memory cell. The switch device is disposed between the dynamic memory cell and the liquid crystal element and uses a control signal to control the connection between the output of the dynamic memory cell and the liquid crystal elements.
