A display device includes a circuit substrate and a light-emitting diode. Two electrodes of the light-emitting diode are connected to two pads of the circuit substrate. Each electrode of the light-emitting diode includes a first conductive layer, a barrier layer, and a metal layer. The first conductive layer is connected to a semiconductor stack layer of the light-emitting diode. The barrier layer is electrically connected to the semiconductor stack layer of the light-emitting diode through the first conductive layer. The adhesion of the material selected for the first conductive layer to the semiconductor stack layer is greater than the adhesion of the material selected for the barrier layer to the semiconductor stack layer. The metal layer electrically connects the barrier layer to the corresponding one of the pads. The melting point of the metal layer is lower than 260 degrees Celsius.
