The invention discloses a touch display screen and a display device. The touch display screen comprises a substrate, a public electrode layer, a driving integrated circuit and multiple touch detection signal lines, wherein multiple gate lines and data lines are arranged on the substrate, the gate lines and the data lines are crossed in an insulated mode to define multiple sub-pixels, at least three columns of adjacent sub-pixels form one pixel column, and the sub-pixels in each column are parallel to the extension direction of the data lines; the public electrode layer is composed of self-capacitance electrodes arranged in an M*N array; the touch detection signal lines are located between every two columns of adjacent sub-pixels, the self-capacitance electrodes are connected to the driving integrated circuit through the touch detection signal lines, and the touch detection signal lines are not arranged between part of every two adjacent pixel columns at least; in a display time period, the driving integrated
