ABSTRACT:
A matrix array of an active matrix liquid crystal display (AMLCD) and a manufacturing method thereof by which aperture ratio is enhanced by an optimum structure design of a line of the matrix array and a thin film transistor (TFT) so as to reduce power consumption, increase luminance, and lower reflection, thus improving contrast ratio. Aperture ratio is increased by forming the TFT above the gate line and providing non-linear TFT. The parasitic capacitor, occurring between the gate busline and the drain electrode, can be reduced when a TFT having the same channel length is manufactured due to effect of channel length extension. Therefore, level shifts of the pixel voltage can be reduced so that flicker is reduced and video quality is enhanced.
