1. A liquid crystal display (LCD) device comprising:
- an LCD panel comprising;
a plurality of data lines for transmitting data signals corresponding to display images;
a plurality of gate lines for transmitting scan signals;
a first sensor signal line coupled to a first bias voltage;
a second sensor signal line coupled to a second bias voltage;
a display unit electrically coupled to a corresponding data line and a corresponding gate line for displaying images based on scan signals and data signals respectively received from the corresponding gate line and the corresponding data line; and
a detecting unit electrically coupled to the second sensor signal line, wherein the detecting unit is electrically connected to the first sensor signal line or electrically isolated from the first sensor signal line based on a touch command; and
a signal processing circuit electrically coupled to the second sensor signal line for outputting corresponding output signals when output signals of the second sensor signal line vary.

Abstract
A liquid crystal display panel includes a first substrate, a second substrate, a first electrode, a second electrode, a third electrode, an isolating layer, and a conductor. The first electrode is disposed between the first substrate and the isolating layer, on which the conductor is disposed. Each of the second and third electrodes is disposed on the second substrate and includes a contact surface. The second and third electrodes are not in contact with each other and are separated by a gap. The conductor is disposed in accordance with the location of the gap.
