This invention is about a lasers indication device which display a portrait on the screen by the use of a deflected laser. To explain in detail, the laser projected from the laser oscillator is deflected horizontally by the galvanometer and then the horizontal deflected laser is deflected vertically by the diffraction lattice. Which is composed of light fiber, epoxy resin and plate glass, and then projected to a liquid crystal cell. The horizontal and vertical deflected laser is passed or intercepted by the control signal at the liquid crystal and then a portrait is displayed on the screen.
