<p>PROBLEM TO BE SOLVED: To precisely form an optical element having both the condenser function of a minute lens and the spectroscopic function of a color filter with a simple process by arranging and constituting plural convex colored minute lenses on a transparent substrate. SOLUTION: This optical element is constituted by arranging plural convex colored minute lenses 2-4 on a transparent substrate 1. In this manufacture of this optical element, for arranging many colored minute lenses 2-4 on a plane, an ink-jet method is used and liquid colored transparent materials 24-26 are arranged selectively on a part becoming the lenses. That is, the liquid colored transparent materials 24-26 colored so as to transmit only respective colors of R, G, B through from ink-jet nozzles 21-23 are applied onto the transparent substrate 1. The liquid colored transparent material 24-26 to be used are constituted of a cured resin raw material for fixing a colorant, pigments or dyestuffs as the colorant for transmitting only a specified color such as R, G, B through and forming the convex lenses and a solvent, etc., dissolving the resin material.</p> |
