Problems solved by technology

However, in the case of an LCD device including a position detection device, the sensitivity of the user's touch may decrease due to the ITO layer 40
That is, when a user touches a predetermined portion of the LCD device, the ITO layer 40 located on the upper side of the LCD device hinders the sensitivity of the user's touch, so it is difficult to accurately detect the touched portion
Especially in the case of a capacitive LCD device that detects a user's touch based on a change in capacitance, the problem of degradation in touch sensitivity is more pronounced

Abstract

An LCD device is disclosed, which comprises first and second substrate confronting each other; a liquid crystal layer between the first and second substrates; and a transparent electrode pattern layer in a predetermined pattern on one surface of the first substrate, which is not confronting the second substrate, for prevention of static electricity and improvement of touch sensitivity, wherein the transparent electrode pattern layer is formed in a predetermined pattern on one surface of the first substrate, which enables to prevent the static electricity during the manufacturing process, and to improve the user's touch sensitivity through the increased resistance of electrode.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2009-0111480 filed on November 18, 2009, which is hereby incorporated by reference as if fully set forth herein. technical field [0003] The present invention relates to a liquid crystal display (LCD) device, and more particularly, to an LCD device capable of detecting a user's touch signal. Background technique [0004] Due to the low driving voltage, the LCD device can achieve low power consumption, and the LCD device is also suitable for portable devices. Accordingly, LCD devices are widely used in various fields such as notebook computers, monitors, spacecraft, and airplanes. [0005] The LCD device includes an upper substrate, a lower substrate, and a liquid crystal layer between the upper and lower substrates. In the case of the LCD device, the alignment state of the liquid crystal molecules in the liquid crystal layer is controlled accordi...
