    • A color electrooptical device is disclosed wherein an active matrix substrate and a color filter substrate face each other and are disposed spaced apart a predetermined distance. A plurality of color filters are formed on the color filter substrate. A protection film is formed on the color filter substrate and on the color filters. The protection film is capable of adhering to the color filters and to a transparent conductive film. The transparent conductive film is formed on the protection film. A metal film is formed on the transparent conductive film which is effective for decreasing the resistivity of the transparent conductive film. A liquid crystal is sealed between the active matrix substrate and the color filter substrate and a plurality of switching elements are formed on the active matrix substrate. The metal film comprises a light blocking chromium film etched into a grid shape. The color filters are formed by electrodeposition onto a previously formed ITO film formed in a striped pattern on the color filter substrate.

    • A picture display device has picture elements disposed in a line and row matrix for applying voltage to liquid crystal material to display a picture in accordance with picture signals applied thereto. The picture signals consist of gate signals sequentially applied to the picture elements along the row directions and video signals simultaneously applied to the picture elements along the line directions. A video signal detecting circuit detects the existence of the picture signals and produces a detection signal whenever the picture signals are temporarily absent for longer than a predetermined time period, and circuitry responds to the detection signal for inverting the polarity of the voltage applied to the liquid crystal material. The video signal detecting circuit may detect the presence of a horizontal or vertical synchronous signal of the video signal, or may compare the average voltage level of the video signal with a reference voltage level, to detect the presence of the picture signals. The inversion of the drive voltage polarity greatly prolongs the life of the liquid crystal and since the inversion is carried out during the time that the picture signals are temporarily interrupted, the inversion of the drive voltage polarity does not disturb the picture or cause picture flicker.
    • 图像显示装置具有设置在行和行矩阵中的图像元素,用于向液晶材料施加电压以根据施加到其上的图像信号显示图像。 图像信号由沿着行方向顺序施加到像素的栅极信号和沿着线方向同时施加到像素的视频信号组成。 视频信号检测电路检测图像信号的存在并且每当暂时不存在图像信号长于预定时间段时产生检测信号,并且电路响应检测信号以反转施加到液体的电压的极性 水晶材料。 视频信号检测电路可以检测视频信号的水平或垂直同步信号的存在,或者可以将视频信号的平均电压电平与参考电压电平进行比较,以检测图像信号的存在。 驱动电压极性的反转极大地延长了液晶的寿命,并且由于在图像信号暂时中断的时间内执行反转,所以驱动电压极性的反转不会影响图像或引起图像闪烁。
