Abstract

An array substrate and its manufacturing method, and a touch display device are disclosed. A display area of the array substrate includes a plurality of thin film transistor (), first transparent electrodes (), second transparent electrodes () and a transparent insulation layer () that contacts the second transparent electrodes (); the transparent insulation layer () is a conductor when a voltage applied thereon is larger than a predetermined voltage, and is an insulator when the voltage applied therein is less than the predetermined voltage. The second transparent electrodes () include first sub-electrodes () arranged into a plurality of rows in a first direction and insulated from each other, and second sub-electrodes () arranged into a plurality of rows in a second direction and insulated from each other, the first direction is intersected with the second direction. The problems such as noise, visual artifacts, insensitive to touch, or the like caused by unbalance of charges can be avoided.
