A polarizer integrated with a transparent conductive film for a liquid crystal display includes a lower film an optical film and a transparent conductive film. A touch panel integrated with the polarizer is formed by attaching an upper sheet to the upper surface of the polarizer integrated with a transparent conductive film. A flat panel display with an integral type touch panel includes a touch panel integrated with the flat panel display having a lower polarizer, a liquid crystal display and an upper polarizer.

A touch panel-mounted liquid crystal panel minimizes picture distortion upon driving of the touch panel. In the liquid crystal panel, a lower glass substrate has switching devices provided in the vicinity of intersections between data lines and gate lines. An upper glass substrate has a black matrix joined to it. Patterned clusters of spacers are positioned at an area corresponding to the black matrix in such a manner to enlarge its contact area with the upper glass substrate, thereby keeping a uniform distance between the upper and lower glass substrates. The enlarged contact area allows the patterned clusters of spacers to sufficiently absorb a pressure load of a finger or a stylus pen. Accordingly, uniform distance between the upper and lower glass substrates is maintained even upon driving the touch panel. As a result, light deterioration and local image distortion is prevented or minimized.

Touch screen structure to prevent image distortion

An in-plane switching mode liquid crystal display device includes first and second opposed substrates having inner surfaces in which a liquid crystal layer formed therebetween, a data bus line and a gate bus line arranged perpendicularly and/or horizontally in a matrix on the first substrate thereby defining a unit pixel region, and a pair of data electrode and common electrode applying a plane electric field in the liquid crystal layer, the electrodes being inclined with respect to the data bus line and parallel to each other.

A position sensing liquid crystal display includes a liquid crystal display panel having a first substrate and a second substrate bonded together, and a position sensing digitizer formed as an integral unit on a first or rear surface of at least one of the substrates, whereby minimizing a display panel thickness and allowing an accurate position sensing.
