A liquid crystal on silicon (LCOS) display device using white light of light emitting diode (LED) as light source is provided. The LCOS display device comprises a white light source, a color separation and polarization device, and a LCOS panel device. The white light source is provided for emitting a white light. The color separation and polarization device is disposed on a light path of the white light, and adapted for separating and polarizing the white light to obtain a plurality of polarized monochromatic lights. The LCOS panel device is disposed on a light path of the polarized monochromatic lights, and the polarized monochromatic lights are partially polarized according to an inputted image signal. Thereafter, the partially polarized monochromatic lights are combined to obtain an output image signal.
