    Abstract: An in-cell touch panel and a display device are disclosed. The in-cell touch panel includes a top substrate and a bottom substrate disposed oppositely to each other, a common electrode layer disposed on a side of the bottom substrate that faces the top substrate and a touch sensing chip. The common electrode layer is partitioned into a plurality of independent self-capacitance electrodes and a plurality of wires for connecting the self-capacitance electrodes to the touch sensing chip. The touch sensing chip is configured to apply common electrode signals to self-capacitance electrodes in a display interval and determine touch positions by detecting capacitance value variation of self-capacitance electrodes in a touch interval. No additional layer is needed for the in-cell touch panel, thereby saving production costs and improving production efficiency.
