The present invention provides an In-Cell touch screen and a display device, which belongs to the field of touch display technology. The FIC capacitive touch screen comprises an array substrate and touch electrodes disposed above or below the array substrate, the touch electrodes comprising a plurality of first capacitive electrodes and a plurality of second capacitive electrodes, wherein the first capacitive electrode comprises a plurality of electrically connected capacitive electrode blocks correspondingly located in areas where at least a portion of sub-pixel units of the array substrate are located. The FIC capacitive touch screen has fewer reports for false touch point.
