Abstract: A head up display (HUD) system and an optical element for an HUD are provided. The optical element includes a Fresnel pattern layer configured to enlarge a virtual image for the HUD, a multiband coating layer formed on the Fresnel pattern layer, the multiband coating layer configured to receive light of multiple wavelength bands from a light source and transmit a portion of the light of the multiple wavelength bands based on a transmittance set with respect to the multiple wavelength bands. The multiple bands may include a wavelength band indicating a red light, a wavelength band indicating a green light, and a wavelength band indicating a blue light.
