ABSTRACT:
An active matrix liquid crystal display includes a number of scan lines, a number of signal lines intersecting the scan lines to cooperate with the scan lines so as to form a matrix. A number of driving thin film transistors are arranged in the form of a matrix and positioned one for each of intersecting points between the scan lines and the signal lines. Each of the driving thin film transistors is connected to one scan line and one signal line. A number of liquid crystal display elements are connected one to each of the driving thin film transistors so that the liquid crystal display elements are selectively driven by the associated thin film transistors. Each of the liquid crystal display elements has a display electrode, a counter electrode opposing the display electrode and a liquid crystal between the display electrode and the counter electrode. The counter electrode has a slit at a region which is opposite to the signal line but which excludes an area where the signal lines and the scan lines are intersected.
