    • In an active matrix liquid crystal display device, the driver of a gate signal line is provided with a low-supply-voltage drive section and a high-supply-voltage drive section. A level shifter circuit in the high-supply-voltage drive section is made up of two CMOS circuits, to which a supply voltage Vdd2 (high-voltage power supply) is applied. Also, to two n-channel TFWs Tr3 and Tr7 in the level shifter circuit is applied a bias voltage Vdd1 (low-voltage power supply) which is a supply voltage different from the above supply voltage. This structure can prevent a high load from being exerted on only one n-channel TFT, thereby being capable of making the withstand voltage high.
    • 在有源矩阵液晶显示装置中,栅极信号线的驱动器设置有低电压驱动部和高电压驱动部。 高电源电压驱动部分中的电平移动器电路由施加电源电压Vdd2(高电压电源)的两个CMOS电路组成。 此外,对于电平移位器电路中的两个n沟道TFW Tr3和Tr7,施加与上述电源电压不同的电源电压的偏置电压Vdd1(低压电源)。 这种结构可以防止高负载仅施加在一个n沟道TFT上,从而能够使耐压高。
