Abstract

The invention relates to a liquid crystal touch screen panel, comprising: a first substrate; a second substrate opposite the first substrate; an electrode pattern unit disposed on the second substrate; and a liquid crystal layer which is made of liquid crystal particles and interposed between the electrode pattern unit and the first substrate. A stimulus applied from an external source onto the first substrate may be sensed based on the variation in the amount of electric charge caused by the external stimulus applied to the first substrate.
