A large number of microscopic recess portions are formed on a surface of a glass substrate in a single dimension or two dimensions by conducting a wet etching through a mask. The large number of microscopic recess portions are aligned densely by again conducting the wet etching but not through the mask. A separating agent is applied upon the surface of the glass substrate and a light-curable or heat-curable resin material of high refractive index is applied thereon. The high refractive index resin material is cured, after piling a first glass substrate upon the high refractive index resin material so as to extend the high refractive index resin material thereon. The high refractive index resin material which is cured and the first glass substrate are separated from the glass substrate, and a low refractive index resin material is applied on the high refractive index resin material which is cured on the first glass substrate. The low refractive index resin material is cured, after piling a second glass substrate on the low refractive index resin material so as to extend the low refractive index resin material thereon.

1. A method for manufacturing a planar micro-lens, having a high refractive index resin material and a low refractive index resin material, being laminated in layers within a region defined between a first glass substrate and a second glass substrate, wherein microscopic cylindrical surfaces or microscopic spherical surfaces are aligned on a boundary surface of the high refractive index resin material and the low refractive index resin material in a single dimension or two dimensions, said method comprising the following first through sixth steps:(First step) a step for forming a large number of microscopic recess portions forming cylindrical or spherical surfaces on a surface of a glass substrate in a single dimension or two dimensions, by conducting a wet etching through a mask upon the surface of the glass substrate as a forming die; (Second step) a step for aligning the large number of the microscopic recess portions densely, by again conducting the wet etching upon the surface of the glass substrate as the forming die on which die microscopic recess portions are formed in the first step, but not through the mask; (Third step) a step for applying a separating agent upon the surface of the glass substrate as the forming die having the microscopic recess portions aligned densely, being formed in the second step, and further for applying a light-curable or heat-curable resin material of high refractive index thereon; (Fourth step) a step for curing the high refractive index resin material, after piling a first glass substrate upon the high refractive index resin material which is applied to the glass substrate as the forming die in the third step so as to cause the high refractive index resin material to extend on the surface thereof; (Fifth step) a step for separating the high refractive index resin material which is cured in the fourth step and the first glass substrate from the glass substrate as the forming die, and for applying a low refractive index resin material on the high refractive index resin material which is cured on the first glass substrate; and (Sixth step) a step for curing the low refractive index resin material, after piling a second glass substrate on the low refractive index resin material which is applied to the high refractive index resin material in the fifth step so as to cause the low refractive index resin material to extend on the surface thereof.
