ABSTRACT:
In an active matrix liquid crystal display panel, each pixel electrode is connected to a first drain bus line through a thin film transistor which is formed adjacent to an intersection between the first drain bus line and an orthogonal gate bus line. A compensating capacitor lower electrode extends from the gate bus line at a position near to a second drain bus line which is adjacent to the pixel electrode in such a manner that the pixel electrode is positioned between the first and second drain bus lines. A compensating capacitor upper electrode is formed integrally with a source electrode of the thin film transistor, to extend along the pixel electrode so as to overlap above the compensating capacitor lower electrode through an insulator layer. Thus, a compensating capacitor is formed of the compensating capacitor lower and upper electrodes and is connected to a gate-source capacitance of the thin film transistor. A change in the gate-source capacitance caused by the positional deviation in the alignment between a gate electrode and the source electrode of the thin film transistor can be compensated by the inverse change in the capacitance of the associated compensating capacitor, without decreasing the aperture ratio of the pixel.
