1. A liquid crystal display (LCD) with an integrated touch screen panel, the LCD comprising:

  • a first substrate having a plurality of pixels formed thereon, wherein each of the plurality of pixels comprises a thin film transistor and a pixel electrode, the pixel electrode being connected to a drain electrode of the thin film transistor through a contact hole formed in a protective layer;

    a second substrate positioned to face the first substrate, the second substrate having a plurality of common electrode patterns formed thereon, wherein the plurality of common electrode patterns are arranged in a first direction to respectively correspond to the pixel electrodes;

    first and second polarizing plates respectively attached to outer surfaces of the first and second substrates;

    a window attached to an outer surface of the second polarizing plate;

    sensing electrodes formed on one surface of one of the second polarizing plate and window, wherein the sensing electrodes are and configured as a plurality of patterns arranged in a second direction, and wherein the second direction intersects the first direction, and wherein the second polarizing layer is positioned at least partially between the sensing electrodes and the second substrate; and

    a liquid crystal layer formed between the first and second substrate.
