LIQUID CRYSTAL DISPLAY DEVICE HAVING TOUCH PANEL
First Claim
1. A liquid crystal display (LCD) device comprising:
- first and second base substrates;
gate lines and data lines formed on the first base substrate and defining a plurality of pixels;
thin film transistors (TFTs) formed in respective pixels;
a black matrix and a color filter layer formed under the second base substrate;
a first electrode formed below the black matrix and to correspond with at least a part of the black matrix;
a second electrode formed on the second base substrate to form a capacitance with the first electrode, wherein a variation of the capacitance is used to detect a touch input to the LCD device; and
a liquid crystal layer formed between the first and second base substrates.

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.
