LIQUID CRYSTAL DISPLAY DEVICE AND FABRICATING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a liquid crystal display device having an image sensing function capable of displaying an image by scanning a document and an image and touch-inputting, and to provide a fabricating method of the device. SOLUTION: The liquid crystal display device includes: a gate line and a data line intersecting each other on a substrate to define a pixel area in which a pixel electrode is positioned; a first thin film transistor positioned at an intersection area of the gate line and the data line; a sensor thin film transistor sensing the light having image information and supplied with a first driving voltage from the data line; and a driving voltage supply line positioned in parallel to the gate line to supply a second driving voltage to the sensor thin film transistor.
