TOUCH SCREEN BUILT-IN TYPE LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a touch screen built-in type liquid crystal display device capable of recognizing touch regardless of illuminance environment of outside light.

SOLUTION: The touch screen built-in type liquid crystal display device includes: a first substrate comprising pixel regions and sensor regions having light sensors for sensing a position of an object coming into contact; a second substrate disposed on one side of the first substrate, comprising color filters formed in regions corresponding to the pixel regions and first light shielding films formed on regions corresponding to the sensor regions; a liquid crystal layer interposed between the first substrate and the second substrate; and a backlight assembly disposed on the other side of the first substrate and providing light for the first substrate and the second substrate.
