    • A liquid crystal display device includes a pixel electrode to which a video signal is supplied and a counter electrode to which a reference signal is supplied in each pixel. In the display device a positive-side gray scale voltage and a negative-side gray scale voltage are formed. The positive-side gray scale voltage and the negative-side gray scale voltage are formed with respect to the reference signal such that an average value of the positive-side gray scale voltage and the negative-side gray scale voltage is increased along with an increase of the signal amplitude of the video signal in the vicinity of the minimum thereof, the average value is decreased along with the further increase of the signal amplitude of the video signal, and the average value is increased along with an increase of the amplitude of the video signal in the vicinity of the maximum thereof.
    • 液晶显示装置包括供给视频信号的像素电极和在每个像素中提供参考信号的对电极。 在显示装置中,形成正侧灰度电压和负侧灰度电压。 相对于参考信号形成正侧灰度电压和负侧灰度电压,使得正侧灰度电压和负侧灰度电压的平均值随着增加而增加 在视频信号的最小值附近的信号幅度的平均值随着视频信号的信号幅度的进一步增加而减小,平均值随着视频信号的幅度的增加而增加 视频信号在其最大值附近。

    • To provide a display device capable of reliably forming a resistive element formed on a substrate including pixels. A display device including at least a thin-film transistor and a resistive element on a substrate has a gate electrode, an insulating film, a semiconductor layer and a conductive layer which are sequentially stacked on the substrate, in which the resistive element is formed by using the semiconductor layer formed between end portions of wiring made of the conductive layer as a resistive body, and at least one conductive layer apart from the end portions is formed on the semiconductor layer between the end portions of wiring.
