Abstract: A color LED display device without color separation comprises a substrate, a plurality of display units, a power supply unit, and a control unit. Each display unit comprises a driving chip, at least one red-light LED chip, at least one green-light LED chip, at least one blue-light LED chip, and a micro optical device assembly. The micro optical device assembly is disposed above the red-light, green-light and blue-light LED chips. When the control unit controls the display unit to emit light, the red-light, green-light and blue-light LED chips emit red, green and blue lights respectively and simultaneously. The red, green and blue lights pass through the micro optical device assembly, such that the light paths of the red, green and blue lights are changed and the three lights are combined on a two-dimensional plane. Therefore, the color separation phenomenon of the conventional color LED display device is solved.
