    Abstract: High precision MEMESs can be manufactured in a large amount without requiring a vacuum process or a lithography process. A film is aligned with a die so as to contact with each other. The film has a functional layer and a releasing layer printed thereon. The die is configured to mold a structure which comprises a functional layer retention part retaining the functional layer and a frame supporting the functional layer retention part. The resin filled between the die and the film is cured. Then, the film is separated from the die so that the functional layer is released from the releasing layer and transferred on the resin cured in the die, thereby the structure is formed.

    Abstract: In this disclosure, there is provided a polarization element comprising a substrate having a predetermined light transmittance in a predetermined wavelength region and a plurality of polarization portions having a wire grid structure on the main surface of the above substrate, wherein the plurality of polarization portions are arranged to ensure that the ratio of the total area of the polarization portions to the predetermined area of the main surface gradually changes along a predetermined direction so that at least one of light transmittance and polarization degree gradually changes in the predetermined direction on the main surface of the substrate. A method for manufacturing the polarization element is also disclosed.

    Abstract: A wire-grid polarizer includes metal reflectors which are embedded in a large number of grooves formed in a one-dimensional grid pattern in the same direction and with the same period in the front surface of a transparent sheet, wherein the average width (a) of the metal reflectors is 200 nm or less, the ratio (b/a) of the average thickness (b) of the metal reflectors from the front side of the sheet to the tip in the backward direction to the above average width (a) is 4 to 25, in any cross-section perpendicular to the surface of the sheet, the shape of each of the metal reflectors in the vicinity of the tip in the thickness direction is such that it gradually becomes thinner in a linear or smoothly curved shape toward the tip, and the ratio of the average length (c) toward the tip of portions that gradually become thinner toward the tip to the above average width (a) is 1.2 or more.
