The invention discloses a touch array substrate, a liquid crystal display panel, and a liquid crystal display device. The touch array substrate includes: a substrate; a touch electrode layer, and the touch electrode layer includes a plurality of touch electrodes insulated from each other. Each touch electrode described above is connected to a touch electrode line; wherein, the touch electrode includes a first groove, and the projected area of the first groove vertically on the substrate is a first area, and the The projected area of the touch electrode lines perpendicular to the substrate is the second area, and the first area and the second area overlap at least in part. The touch array substrate reduces the surface area of the part of the touch electrodes overlapping with the touch electrode lines through the first groove overlapping with the touch electrode lines, thereby reducing the distance between the touch electrode lines and the touch electrodes. The parasitic capacitance reduces the load between the touch electrode line and the touch electrode.
Description
technical field [0001] The present invention relates to a display device, in particular to a touch array substrate, a liquid crystal display panel and a liquid crystal display device. Background technique [0002] Liquid Crystal Displays (LCDs) are widely used in various display devices such as smart phones, notebook computers, and monitors due to advantages such as good portability and low power consumption. [0003] Currently, touch screens can be classified into plug-in touch screens, surface-covered touch screens, and built-in touch screens according to the positions of touch electrodes. Among them, the plug-in touch screen directly adds touch electrodes outside the LCD. This method makes the overall thickness of the whole machine thicker and the light transmittance becomes lower. Covering the surface touch screen is to make touch electrodes outside the color film substrate of the LCD. This method reduces the thickness of the whole machine, but increases the manufacturi...
