Abstract

The present invention discloses an array substrate, a liquid crystal display panel and a touch display device. The array substrate comprises: a base substrate, as well as a touch trace layer including a plurality of touch traces, a first insulating layer, touch electrode layer including a plurality of touch electrode blocks in matrix arrangement, a second insulating layer, and a pixel electrode layer including a plurality of pixel electrodes in matrix arrangement and a bridge structure, which are disposed on the base substrate in sequence, wherein the touch traces are electrically connected to the corresponding touch electrode blocks by means of the bridge structure; the bridge structure fills up and runs through first via holes of the second insulating layer that expose the touch electrode blocks and run through second via holes of the second insulating layer and the first insulating layer that expose the traces; and the bridge structure is located between every two adjacent columns of pixel electrodes, and the first via holes and the second via holes that the bridge structure correspondingly fills up are spaced apart by at least one row of pixel electrodes. With the technical solution provided in the present invention, risks of short-circuiting between the bridge structure and the pixel electors are reduced, and the yield of manufacturing of liquid crystal display panels is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of touch technology, and in particular, to an array substrate, a liquid crystal display panel and a touch display device. Background technique [0002] At present, the touch wires in the touch display device need to be electrically connected to the touch electrode blocks corresponding to the touch electrode layer. Generally, the pixel electrode layer is used to bridge the touch wires and the corresponding touch electrode blocks. Specifically, The implementation method is to use the pixel electrode layer to form a cross-bridge structure. The bridge structure connects each touch electrode block with the touch trace through the shallow hole extending to the touch electrode layer and the deep hole extending to the touch trace layer. The touch traces corresponding to the layers are electrically connected. Generally corresponding to each touch electrode block, the deep holes and shallow holes corr...
