To improve the image quality of thin and lightweight head-mounted displays with hologram optics and polarized laser backlight liquid crystal displays, we analyzed ghosts of the fabricated benchtop prototype. The ghosts are caused by the reflections on the surfaces of quarter waveplates and holographic optical element. Based on the analysis, we obtained a clear image by suppressing surface reflections.
