1. a TFT array base palte comprises the effective pixel area that is made up of grid line, data wire, TFT, pixel electrode and public electrode;

  • It is characterized in that, also comprise;

    In the outside of the grid line at said effective pixel area edge, also be provided with and said grid line with the test grid line of layer, each interior bar data wire of said test grid line and said effective pixel area intersects to form a plurality of test zones;

    In each said test zone, the test source electrode that be formed with the test grid that is electrically connected with said test grid line, measuring semiconductor active layer, is electrically connected, and test drain electrode with data wire in the said effective pixel area;

    In each said test zone, also be formed with the test contact zone that is electrically connected with said test drain electrode.
