Abstract A colored microlens array which functions as both a color filter array of different color filter layers and transparent microlenses. The colored microlens array has a transparent basic layer and a plurality of colored microlenses of different colors formed on the transparent basic layer in two dimensional arrangement in accordance with at least one basic color arrangement pattern. The colored microlenses are manufactured by forming semispherical lens forming layer portions on the respective color filter layers of the color filter array and by etching the color filter layers with the formed semispherical lens forming layer portions as a mask, to change in shape the respective color filter layers into the semispherical lenses, respectively. The colored microlenses are applied to solid-state image sensing devices, color liquid crystal display units, etc.
A colored microlens array, comprising: a transparent basic layer; and a plurality of colored microlenses of different colors, each colored microlens serving as a color filter, formed on said transparent basic layer in a two dimensional arrangement in accordance with at least one basic color arrangement pattern, wherein a thickness of said transparent basic layer differs according to a color of a colored microlens formed thereon such that foci of said colored microlenses are located substantially on the same plane.
