<p>An active matrix circuit for liquid crystal displays is disclosed. The circuit comprises a plurality of liquid crystal pixels arranged in a matrix (C11, Ci2, C21, C22) a plurality of scanning lines (Xl, X2, X3) applied with selection pulses for selecting rows of the pixel matrix, a plurality of signal lines (Y1, Y2, Y3) applied with signal voltages for being applied to the pixels in a selected row, and a plurality of switching elements (T11a), responsive to the respective selection pulses to apply the signal voltages to the respective pixels. Each pixel (C11) is controlled by two switching elements (T11a, T11b) reponsive to selection pulses applied to adjacent two scanning lines (X1, X2). If one of the two switching elements is defective e.g. during a manufacturing process, it may be later electrically isolated from the circuit. The other one can control the respective pixel to operate normally. The switching elements may be transistors or non-linear devices.</p> |
