Abstract
The invention provides a manufacturing method for display panel, display panel and display device. The display panel comprises a plurality of pixel units. Each pixel unit comprises a light-emitting element and a TFT, the light-emitting element comprises: an anode and a first touch electrode, disposed in a same layer, a light-emitting layer disposed on the anode and the first touch electrode, and a first electrode disposed on the light-emitting layer. The first electrode serves as a cathode of the display panel and a second touch electrode of the display panel in a time division manner. As such, the invention can reduce the thickness of the display panel and thickness of display device.
