Abstract:
1. A stereoscopic liquid crystal display device, comprising: a liquid crystal panel configured by including a first substrate and a second substrate facing into each other, and a first liquid crystal layer filled between the first and second substrates; an adhesion layer formed on the liquid crystal panel; and a touch and stereoscopic image lens layer as a single panel formed on the adhesion layer including a third substrate and a fourth substrate facing into each other and a second liquid crystal layer between the third and fourth substrates, a plurality of first electrodes formed at each lens region on the third substrate, a second electrode formed on an entire surface of an inner surface of the fourth substrate facing into the second liquid crystal layer, and a third electrode and a fourth electrode formed on an outer surface of the fourth substrate for detecting a touch position, wherein the first electrodes comprise a first group of first electrodes directly on the third substrate and a second group of first electrodes formed on a different layer from the first group, and the first and second group of first electrodes are alternately positioned, wherein an electrically-driven liquid crystal lens is defined in the touch and stereoscopic image lens layer by applying a voltage value gradually increasing from a center portion to an edge portion for each lens region to the first electrodes, and by applying a voltage value to the second electrode as the same voltage value with the applied voltage value to the center portion of the first electrode.
