Abstract

A touch panel and a touch device comprising the touch panel. The touch panel comprises a substrate; a display function stack on a side of the substrate; and a touch layer on a side of the display function stack away from the substrate. The touch layer and the display function stack are electrically connected to a flexible circuit board via a substrate wiring layer.
