    • A liquid-crystal electro-optical device capable of compensating for the operation of any malfunctioning one of TFTs (thin-film transistors) existing within the device if such a malfunction occurs. Plural complementary TFT configurations are provided per pixel electrode. Each complementary TFT configuration consists of at least one p-channel TFT and at least one n-channel TFT. The input and output terminals of the plural complementary TFT configurations are connected in series. One of the input and output terminals is connected to the pixel electrode, while the other is connected to a first signal line. All the gate electrodes of the p-channel and n-channel TFTs included in said plural complementary TFT configurations are connected to a second signal line.
    • 如果发生这种故障,则能够补偿设备内存在的任何故障的TFT(薄膜晶体管)的操作的液晶电光器件。 每像素电极提供多个互补TFT配置。 每个互补TFT配置由至少一个p沟道TFT和至少一个n沟道TFT组成。 多个互补TFT结构的输入和输出端子串联连接。 输入和输出端之一连接到像素电极,而另一个连接到第一信号线。 包括在所述多个互补TFT配置中的p沟道和n沟道TFT的所有栅电极连接到第二信号线。
