Abstract:
A touch liquid crystal display panel and a method for manufacturing the same are provided. The touch liquid crystal display panel comprises a sensing layer comprising a plurality of electrode regions arranged as an array, the electrode regions being electrically isolated from one another and respectively corresponding to a plurality of pixel units of a display region, and a wiring layer comprising a plurality of wires electrically connected with a control chip. The electrode regions each are electrically connected with a corresponding wire of the wiring layer through a via hole disposed adjacent to part of sub pixels of a corresponding pixel unit, so that the control chip acquires an inductive signal of each of the electrode regions. In the present disclosure, only partial sub pixels are provided with via holes for forming electric contact of the electrode regions of the sensing layer with the wires of the wiring layer. The aperture ratio of the self-capacitive screen can be increased through reducing the number of via holes. In the meantime, the transmittance of the entire display panel can be improved.
