A patterned optical retarder including non-overlapping first (21) and second (27) regions with respective first and second major surfaces having different RMS surface roughnesses. For substantially normally incident light over a wavelength range from about 400 nm to about 1000 nm, the optical retarder has different retardances in the respective first and second regions.

This method for manufacturing a light absorber includes: a first step for irradiating a resin substrate with ion beams; a second step for etching the irradiated resin substrate with an alkaline solution to form an uneven surface on the surface thereof; a third step for forming a transfer body which covers the uneven surface of the etched resin substrate; and a fourth step for peeling off the transfer body from the resin substrate to obtain a light absorber. A metal film, a photocurable resin, and a silicone rubber are disclosed as an example of the transfer body.

The invention relates to an item comprising a substrate having at least one main surface coated with a multilayer interferential coating comprising at least one layer with a refractive index higher than 1.65 and at least one layer with a refractive index lower than, or equal to, 1.65, at least one of the layers of the interferential coating being an organic-inorganic layer that has been deposited in a vacuum environment and has a thickness of at least 30 nm, said interferential coating having a thickness of at least 450 nm and/or at least 8 layers.

Optically transparent fiber glass cover substrates for electronic displays. The cover substrates include an optically transparent fiberglass composite layer including a fiberglass layer embedded in a matrix material and an optically transparent hard-coat layer bonded to a top surface of the optically transparent fiberglass composite layer. A bottom surface of the optically transparent fiberglass composite layer may define a bottommost exterior surface of a cover substrate. The bottommost exterior surface of a cover substrate may be disposed over a display surface of an electronic display to protect the display surface from damage.

A high refractive index coating made by forming a solid thin layer of a polymer such as P4VP by a process such as iCVD and halogenating the solid layer to thereby form a film that has a greatly increased refractive index and other desirable optical and physical properties.

Visibility of an optical film at the time of handling can be improved, and an antireflection region and a visible region can be easily formed on a surface of the optical film in an identical processing step. An optical film 1 includes a base material 11 having flexibility and a resin layer 12 laminated on at least one of surfaces of the base material 11. The resin layer 12 includes a concave-convex pattern region 2 in which a micro concave-convex structure 20 composed of a plurality of convexities 21 or concavities 22 arrayed at a pitch P less than or equal to a wavelength of visible light are formed and a strip-shaped line marker region 3 in which a plurality of ridge portions 31 arrayed at intervals from one another at a track pitch P.sub.t more than or equal to the wavelength of visible light are formed.
