  Holographic displays can represent real three-dimensional (3D) images. A key characteristic of holographic display is viewing angle. The viewing angle depends on the pixel size for showing holographic patterns. 3D holographic display with 1 μm pixel size can represent 3D images that viewing angle is over 30 degrees. We developed magneto-optic 3D display (3D-MOSLM) with 1 μm magnetic pixel size by thermomagnetic recording method. However, this conventional 3D-MOSLM could show only green and red colors because reference lights were only green and red colors. In addition, thickness of magnetic garnet films was designed for only green and red colors. In this study, we developed colorized 3D-MOSLM using an optical space division method. The thickness of magnetic garnet films was designed for each color. The colorized 3D-MOSLM could represent 3D images with blue, green and red colors.
