Abstract
A colored microlens array includes a plurality of microlenses for focusing incident light on a plurality of respective positions, on a substrate or a transparent film provided on the substrate, in which peripheral sections of the plurality of microlenses overlap each other at the adjacent positions and the microlenses are colored in a plurality of colors and arranged in a predetermined color arrangement.
Claims14
A method for manufacturing a colored microlens array, comprising:
- a photosensitive material forming step of evenly forming a photosensitive material colored with pigment or dye, on a substrate or a transparent film formed on the substrate;
- a lens shape forming step of irradiating light selectively on a predetermined portion of the photosensitive material and subsequently performing development processing to form a surface of the photosensitive material into a lens shape;
- and
- wherein a masking means having light transmissivity adjusted incrementally and consecutively by a light shielding film is used in the lens shape forming step so as to form a plurality of microlenses into respective lens shapes when the surface of the photosensitive material is formed into a lens shape by selectively irradiating light on a predetermined portion of the photosensitive material.
