    A hybrid diffractive-refractive 60° field of view (FOV) eyepiece for head-mounted display (HMD) with a three-layer diffractive optical element (DOE) is designed, and the design performance is given. The diffraction efficiency of the three-layer diffractive optical element is larger than 90% at each FOV and wavelength in designed band, so that the utilization rate of energy and contrast ratio of image can be improved. The system has an 8 mm exit pupil and a 22 mm eye relief, and the feature of 8 g weight and 26.8 system size guarantee the lightness and compactness of the structure, which are well to be a eyepiece for HMD.
