1. A liquid crystal display apparatus comprising:

  • a first substrate;

    a second substrate opposing the first substrate;

    a plurality of scanning lines which are formed on a side of the first substrate and extend in one direction;

    a plurality of data lines which are formed on the side of the first substrate and extend in a direction crossing the scanning lines;

    a plurality of thin film transistors each of which is provided in a vicinity of a respective crossing region of the scanning lines and the data lines on the side of the first substrate, each transistor including a semiconductor thin film, a gate electrode arranged on a side of the semiconductor thin film and source and drain electrodes respectively connected with source and drain regions of the semiconductor thin film;

    a plurality of pixel electrodes each of which is connected with a respective one of the thin film transistors and which are arranged with a space between adjacent pixel electrodes;

    an electroconductive layer which is provided between the pixel electrodes and the scanning lines and the data lines to cover the data lines, the electroconductive layer being disposed in a region including the spaces between the adjacent pixel electrodes and superimposed on at least parts of peripheral portions of the pixel electrodes, and applied with a common potential;

    an insulating film formed between the pixel electrodes and the electroconductive layer;

    at least one opposed electrode formed on a side of the second substrate to correspond to the pixel electrodes; and

    a liquid crystal provided between the pixel electrodes and said at least one opposed electrode;

    wherein the electroconductive layer comprises a light-shielding, electroconductive film which has a width smaller than a width of the spaces between the adjacent pixel electrodes and a transparent electroconductive film which has a width larger than the width of light-shielding electroconductive film.
