LIQUID CRYSTAL DISPLAY DEVICE WITH TOUCH FUNCTION

摘要

A liquid crystal display device includes multiple data lines and multiple scan lines insulatedly intersecting each other. Each of the pixel units includes a common electrode and a pixel electrode insulated from each other by an insulating layer, an in-plane electric field is formed by the common electrode and the pixel electrode The common electrodes are connected together to form a common electrode layer, which comprises multiple touch electrodes and touch signal wires. Each of the touch signal wires is electrically connected with a corresponding touch electrode, first slits are arranged in parallel to the data lines, each of the first slits is disposed between two adjacent touch electrodes or between a touch electrode and an adjacent touch signal wire, except at a junction between the touch signal wire and the touch electrode. A first slit overlaps with a pixel electrode within a pixel unit.
