PURPOSE: An optical projection type micro-display having a spatial filter for eliminating a pixel grid pattern is provided to remove the pixel grid pattern that is generated by a conductor wire for controlling liquid crystal display of a liquid crystal screen. CONSTITUTION: An optical projection type micro-display having a spatial filter(40) for eliminating a pixel grid pattern includes a liquid crystal screen, a video signal output part, a lighting device, a plurality of lenses, and a spatial filter. The liquid crystal screen is constructed in a manner that a plurality of conductor wires to which voltage is applied to control liquid crystal are arranged in a grid structure. The video signal output part generates a video signal to the liquid crystal screen. The lighting device illuminates the back of the liquid crystal screen. The lenses transmit, magnify and reduce an image of the liquid crystal screen to focus the image on a screen. The spatial filter has four optical stoppers(42,43) and is located on the focal plane of one of the lenses to block lights of low-frequency regions of X- and Y-axes other than the center point of the projected image.
