Liquid crystal display device and method for manufacturing the same

Abstract

A liquid crystal display device and a method for manufacturing the same are disclosed. The liquid crystal display device comprises gate and data lines arranged to cross each other on a substrate to define a plurality of pixels; a pixel electrode formed in each of the plurality of pixels; a common electrode forming an electric field together with the pixel electrode, patterned to sense a touch of a user; a sensing line discontinuously formed on the common electrode and electrically connected with the common electrode; a jump line formed below the common electrode to electrically connect discontinuous portions of the sensing line with one another; and first and second connection electrodes for electrically connecting the jump line with the sensing line, wherein the first connection electrode is connected with the jump line, and the second connection electrode is connected with the sensing line and the first connection electrode respectively. Because the common electrode is used as a sensing electrode, an independent touch screen is not needed on the liquid crystal panel.

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2010-0116166 filed on Nov. 22, 2010, which is hereby incorporated by reference as if fully set forth herein. technical field [0003] The present invention relates to liquid crystal displays, and more particularly, to liquid crystal displays having sensing electrodes for sensing a user's touch. Background technique [0004] Liquid crystal displays are widely used in many fields of notebook computers, monitors, spacecraft and aircraft, etc. because of advantages of low power consumption and portability based on low driving voltage. [0005] A liquid crystal display includes a lower substrate, an upper substrate, and a liquid crystal layer formed between the lower substrate and the upper substrate. In a liquid crystal display, the alignment state of liquid crystal molecules in the liquid crystal layer is controlled according to whether an electric f...

Problems solved by technology

[0013] However, in the aforementioned prior art liquid crystal display, since the touch screen 20 is separately formed on the liquid crystal panel 10, the total thickness of the liquid crystal display increases due to the touch screen 20.

Therefore, there is a problem that the manufacturing process steps are complicated and the manufacturing cost is increased
