The invention discloses a micro light-emitting diode display panel and a display device. The micro light-emitting diode display panel comprises an upper substrate, a lower substrate, an upper electrode, a lower electrode, a first micro light-emitting diode, a second micro light-emitting diode, a third micro light-emitting diode and an image sensor array, wherein the upper substrate and the lower substrate are arranged in a spacing mode in a first direction; the upper electrode is arranged at the side, close to the lower substrate, of the upper substrate, and the lower electrode is arranged atthe side, close to the upper substrate, of the lower substrate; and the first micro light-emitting diode, the second micro light-emitting diode, the third micro light-emitting diode and the image sensor array are all arranged between the upper electrode and the lower electrode, and the first micro light-emitting diode, the second micro light-emitting diode, the third micro light-emitting diode andthe image sensor array are distributed in a spacing mode along a second direction. The micro light-emitting diode display panel has a scanning function in addition to excellent display performance.
