The present invention generally relates to a laminated image panel and a fabrication method thereof for projecting images projected from an image optical engine, on a screen by reflecting and/or transmitting the images. The laminated image panel in accordance with the present invention comprises front elements, rear elements disposed in opposition to the front elements, sealants for forming a predetermined cell by mutually bonding opposed rim parts of the front elements and the rear elements and for sealing the front and rear elements by separating the front elements from the rear elements at certain intervals, and a diffusing medium injected into the cell and uniformly diffusing the projection images in transparent and/or semitransparent state. The diffusing medium is created, in a predetermined ratio, by mixing a water-soluble polymeric material that forms a transparent solution by being dissolved in water, a light curable hydrophilic monomer having hydrophilicity and a high dispersion in water, a photoinitiator for inducing a polymerization by interacting with the light curable hydrophilic monomer, and a solvent.
