The present invention relates to a device for forming a visible image which can draw a two-dimensional or a three-dimensional visible image without having a scanning locus of a laser beam recognized.The device for forming a visible image of the present invention is comprised of a laser source irradiating a laser beam in an invisible region, a scanning means for scanning said laser beam two-dimensionally or three-dimensionally, a condensing optical system for condensing said laser beam to a drawing scheduled point in the air for plasma emission of a gas, and a controlling means for controlling oscillation timing of said laser source and scanning timing of said scanning means so as to generate said plasma emission at said drawing scheduled point in a time series and for drawing a visible image as a residual image phenomenon of the plasma emission.
