Patent ID: 7817337

Claim:
A laminated image panel for realizing projection images by reflecting transmitting, and diffusing the images projected from an image optical engine, comprising: front elements; rear elements disposed in opposition to the front elements; sealants mutually sealing/bonding opposed mm parts of the front elements and the rear elements while separating the rim parts at certain intervals, and forming a predetermined cell surrounded by the front elements, the rear elements, and the rim parts; and a diffusing medium for uniformly diffusing the projection images in transparent and/or semitransparent state by being injected into the cell; and wherein the diffusing medium is made of the polymeric material obtained by a light curing composition, and the light curing composition comprises: 0.5% to 35% of a water soluble polymeric material, based on overall weight of the light curing composition and said material being dissolved in water and turning the light curing composition into a transparent solution; 31% to 98.5% of a light curable hydrophilic monomer, based on overall weights of the light curing composition and said monomer having hydrophilic property and a high dispersion in water; 0.1% to 5% of a photoinitiator, based on the overall weight of the light curable hydrophilic monomer and said initiator inducing a polymerization by interacting with the light curable hydrophilic monomer; and 0.5% to 35% of a solvent, based on overall weight of the light curing composition.
