Disclosed are an In-Cell touch screen and a display apparatus, the In-Cell touch screen comprising: an array substrate; an opposed substrate arranged to be opposed to the array substrate; a conductive black matrix provided on one side of the array substrate facing the opposed substrate or on one side of the opposed substrate facing the array substrate. The black matrix comprises a plurality of first touch electrodes and a plurality of second touch electrodes arranged to be insulated from each other and alternate with each other, one of the first touch electrode and the second touch electrode is applied with a touch scan signal, and the other one of the first touch electrode and second touch electrode is coupled with the touch scan signal and outputs a touch sensing signal. No separate touch electrode made of ITO material is required, and a pattern of the black matrix is provided in a non-opening region of the pixels, thus the light transmittance of the display apparatus can be prevented from being adversely affected by the touch electrode. Further, a mutual capacitance in a thickness direction of the touch screen is avoided, thus the touch sensitivity of the In-Cell touch screen can be improved.
