Abstract
A touch panel and a display device are disclosed. The touch panel comprises: a plurality of self-capacitance electrodes (04) disposed in a same layer and independent from each other; a plurality of wires (05) connecting the self-capacitance electrodes (04) to a margin frame of the touch panel; and periphery wirings (07) located at the margin frame of the touch panel and connected with the wires (05) one to one. Each of the wires (05) is electrically connected with at least two self-capacitance electrodes that are provided non-adjacent to each other (04) and self-capacitance electrodes (04) electrically connected with different wires (05) do not overlap each other. The touch panel can reduce touch dead zone in the touch panel utilizing self-capacitance principle.
