Abstract

The invention relates to a liquid crystal display device including a touch panel, specially to a liquid crystal display device in which a touch panel is embedded in a liquid crystal panel, which reduces the number of processes and eases assembly. The liquid crystal display device includes first and second substrates opposite each other, a thin film transistor array formed on the first substrate,a touch sensing part formed on the second substrate including a plurality of transparent X electrodes, a plurality of transparent Y electrodes orthogonally intersecting each other and a first transparent insulating film between the X electrodes and the Y electrodes, a color filter array formed on the touch sensing part, and a liquid crystal layer formed between the thin film transistor array and the color filter array.

Description

[0001] This application claims priority from Korean Patent Application No. P08-090236 filed on September 12, 2008, which is hereby incorporated by reference in its entirety for all purposes. technical field [0002] The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device in which a touch panel is embedded in a liquid crystal panel, thereby contributing to a reduction in the number of processes and easy assembly. Background technique [0003] With the continuous improvement of modern society's dependence on information, the field of display for visually displaying electronic information signals is developing rapidly. Accordingly, various flat panel display devices having excellent properties such as thin thickness, light weight and low power consumption have been developed, and they have rapidly replaced general cathode ray tubes (CRTs). [0004] Examples of flat panel display devices include, for example, li...
