A micro light-emitting diode display device includes a circuit substrate and a plurality of display pixels. The display pixels are arranged on the circuit substrate and are respectively electrically connected to the circuit substrate. Each display pixel includes a plurality of micro light-emitting elements. In each display pixel, a part of the micro light-emitting elements form at least one series-connection structure, and the micro light-emitting elements of the series-connection structure are within a wavelength range of the same lighting color. The circuit substrate respectively provides a same driving voltage to drive the micro light-emitting elements included in the series-connection structure of each display pixel and the micro light-emitting elements excluded from the series-connection structure.
