Multiview display has attention owing to its smooth motion parallax, visual discomfort alleviation, and wide depth of focus. Nevertheless, its applications are limited because of the freedom to design ultrathin display systems. This paper proposes a novel method to design the system freely by using ultrathin metasurface in conjunction with a flat panel to reduce the system&#x0027;s complexity. We demonstrate ultrathin metasurface for red (637nm), green (532nm), and blue (457nm) wavelengths by using the look-up table method, and the subpixel of the metasurface are mapped according to the pixel arrangements of the LCD panel. The proposed 3D multiview display system produces 8 views at the optimal distance of 1000mm from the LCD screen. Numerical simulation is implemented to verify the effectiveness of proposed method and the results show that it can achieve a multiview 3D display with high quality. The thickness of metasurface is 2&#x03BC;m. The proposed metasurface for multiview display has great potential to underpin the development meta-optics-based operations in the field of integrated optics and imaging
