A head-up displayincludes a MEMS mirror componentfor displaying images and a combinerfor reflecting light from the MEMS mirror componentso that an observer observes reflected light as a virtual image and for transmitting ambient light. The combinerincludes a green light reflecting portionfor selectively reflecting mainly green light in a green light wavelength region, a red light reflecting portionfor selectively reflecting mainly red light in a red light wavelength region, and a blue light reflecting portionfor reflecting blue light in a blue light wavelength region. The light reflecting portionstoare laid in layers. The green light reflecting portionis arranged the closest to the MEMS mirror component
