Abstract
An in-cell touch panel and a display device are disclosed. The in-cell touch panel includes: an upper substrate and a lower substrate arranged opposite to each other, a plurality of mutually independent self-capacitance electrodes arranged in the same layer, and a plurality of leads configured to connect the self-capacitance electrodes to a touch detection chip. The self-capacitance electrodes and the plurality of leads are arranged in different layers; an interlayer insulating layer is disposed between the self-capacitance electrodes and the leads; each self-capacitance electrode is electrically connected with the lead via a through hole running through the interlayer insulating layer; and the interlayer insulating layer is provided with recessed portions at overlapped areas of the self-capacitance electrodes and the leads other than the leads electrically connected with the self-capacitance electrodes. Therefore, the uniformity of display images of the touch panel can be improved.
