Abstract: The present disclosure relates to the technical field of display, and provides a display substrate and a display panel, capable of solving the problem in existing display products of light interference during touch sensing. The display substrate of the present disclosure comprises: a light-emitting device layer configured to emit first-color light; a quantum dot layer at least comprising a first quantum dot unit and a second quantum dot unit, the first quantum dot unit being configured to emit second-color light under the excitation of the first-color light, and the second quantum dot unit being configured to emit third-color light under the excitation of the first-color light; a touch sensing layer configured to determine touch information on the basis of an optical signal received by the touch sensing layer; and an auxiliary functional layer arranged between the quantum dot layer and the light-emitting device layer, wherein the auxiliary functional layer is configured to transmit the first-color light and reflect the second-color light and the third-color light, thereby reducing the interference of the second-color light and the third-color light with the touch sensing layer, and improving the accuracy and sensitivity of the touch sensing layer.
