<p>An active matrix liquid crystal display device in a normally white mode comprises two bus lines (9, 10) corresponding to pixels electrodes (4). The bus lines (9, 10) are formed under the pixel electrodes (4) with an insulating layer (11) interposed therebetween. First and second alternating current voltages whose phases differ from each other by 180 DEG , are applied to the bus lines (9, 10). The first and second voltages satisfies an equation of C1.V1 = C2.V2 (V1 and V2 represent first and second voltages, respectively, and C1 and C2 represent capacitances between the bus lines (9, 10) and the pixel electrodes (4), respectively). A pixel electrode (4) having represented a bright spot defect is short-circuited with one of the bus lines (9), and the voltage of the bus line (9) is applied to the pixel electrode (4). The bright spot defect is therefore changed to a dark spot defect. <IMAGE></p> |
