Abstract
A liquid crystal display device including a touch panel having a simple structure and minimized thickness is provided. The liquid crystal display (LCD) device according to an embodiment includes a liquid crystal panel and a touch panel structure. The liquid crystal panel includes a thin film transistor (TFT) array substrate, a color filter substrate having a black matrix therein, and a liquid crystal layer disposed between the TFT array substrate and the color filter substrate. The touch panel structure includes at least one touch sensor. Each touch sensor includes a first electrode disposed within the liquid crystal panel, and a second electrode disposed outside the liquid crystal panel.
