1. a liquid crystal indicator has a plurality of pixels of arranging by rectangular, and described a plurality of pixels have respectively:

  • Liquid crystal capacitance, its by the thin film transistor (TFT) that adopts top gate type carry out switch pixel electrode, and the opposed opposite electrode of described pixel electrode and described pixel electrode and described opposite electrode between the liquid crystal layer that disposes form;

    WithWith described liquid crystal capacitance the 1st auxiliary capacitor and the 2nd auxiliary capacitor that is electrically connected in parallel;

    Described the 1st auxiliary capacitor, by the 1st auxiliary capacitance electrode that is electrically connected with described pixel electrode, and opposed the 1st auxiliary capacitor opposite electrode of described the 1st auxiliary capacitance electrode and be disposed at described the 1st auxiliary capacitance electrode and described the 1st auxiliary capacitor opposite electrode between the 1st dielectric layer formDescribed the 2nd auxiliary capacitor, by the 2nd auxiliary capacitance electrode that is electrically connected with described pixel electrode, and opposed the 2nd auxiliary capacitor opposite electrode of described the 2nd auxiliary capacitance electrode and be disposed at described the 2nd auxiliary capacitance electrode and described the 2nd auxiliary capacitor opposite electrode between the 2nd dielectric layer formDescribed the 1st auxiliary capacitor opposite electrode and described the 2nd auxiliary capacitor opposite electrode, be and described the 1st auxiliary capacitor and the common unitary electrode of described the 2nd auxiliary capacitor,Described the 1st dielectric layer is the part of gate insulating film that covers the semiconductor layer of described thin film transistor (TFT),Described the 2nd dielectric layer is to supply with the part of the interlayer dielectric that the scanning lines of sweep signal cover to described thin film transistor (TFT), and with than the thinner mode of other parts of described interlayer dielectric optionally by filming.
