An ambient light rejecting screen used in a laser light source projector, which generates a light with a first wavelength and a light with a second wavelength, is provided. The screen includes a base, a light absorbing layer, a first filter layer and a second filter layer. The light absorbing layer is disposed on the base. The first filter layer is disposed on the light absorbing layer. The crystallization characteristic of the first filter layer corresponds to the light with the first wavelength and generates a reflective light with the first wavelength, and allows the light with remaining wavelengths to pass through. The second filter layer is disposed on the light absorbing layer. The crystallization characteristic of the second filter layer corresponds to the light with the second wavelength used to generate the reflective light with the second wavelength and allows the light with remaining wavelengths to pass through.
