Abstract

The invention provides a liquid crystal touch display panel, which is characterized in that through holes are formed in an opening area of a planarization layer and two sides of a metal layer, and a reinforcing layer is arranged on the surface of a common electrode; The panel has beneficial effects that compared with a liquid crystal touch display panel, the thorugh holes are formed in the two sides of the opening area, bending of a line changing layer of the common electrode in the opening area is gentle, stress is small, fluctuation in the manufacturing process can be effectively avoided, notches are eliminated, the problem that a common electrode is thin and prone to breakage is solved, meanwhile, a reinforcing layer is additionally arranged on the surface of the wire changing layer, the film thickness of the common electrode layer in the opening area is increased, and therefore breakage of the common electrode can be further avoided, and the yield of products is effectively increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal touch display panel. Background technique [0002] At present, the integrated touch display panel mainly includes two types: the on-cell type in which the touch sensor is arranged between the polarizer of the display panel and the color filter substrate; and the on-cell type in which the touch sensor is embedded Embedded into the pixel structure of the display panel (In-Cell). [0003] figure 1 For existing embedded touch display panels, such as figure 1 As shown, the touch display panel 100 includes an array substrate 101, a color filter substrate 103, and a liquid crystal layer 102 located between the array substrate 101 and the color filter substrate 103. The array substrate 101 includes a base 1011, and metal tracks prepared on the surface of the base 1011. The wiring layer 1012 and the planarization layer 1013 covering the metal wiring layer 1012. The pl...
