Abstract
A liquid crystal display device having optical sensors, for sensing a touch, embedded in a liquid crystal panel to improve touch sensitivity is disclosed. The liquid crystal display device includes pixel regions spaced from each other on a first substrate, gate lines formed to separate the pixel regions in a first direction, driving voltage lines parallel to the gate lines, data lines formed between the pixel regions in a second direction intersecting the first direction, storage lines parallel to the driving voltage lines, read-out lines separated from neighboring data lines by one pixel region in the second direction, display transistors formed at intersections of the gate and data lines, pixel electrodes formed in the pixel regions, output switching transistors formed between the gate and read-out lines, capacitors formed between the output switching transistors and storage lines, and photo sensing transistors formed on the output switching transistors and storage lines.
