1. a manufacture method for liquid crystal indicator, is characterized in that, comprising:

  • Substrate is provided;

    Form light blocking layer and thin-film transistor structure layer successively on the substrate, described thin-film transistor structure layer comprises and is formed directly into gate metal layer on described light blocking layer and gate insulator;

    Adopt multidomain half gray tone mask plate to carry out single exposure, development, with thin-film transistor structure layer and light blocking layer described in patterning, the light blocking layer of patterning is consistent with the width of the gate metal layer on it and gate insulator;

    Described substrate and partially patterned light blocking layer are formed and the gate metal layer of patterning and gate insulator color blocking layer arranged side by side.
