    Abstract: A synthetic polymer film whose surface has a plurality of raised or recessed portions, wherein a two-dimensional size of the plurality of raised or recessed portions is in a range of not less than 0.5 μm and not more than 3 μm when viewed in a normal direction of the synthetic polymer film, the synthetic polymer film has a crosslink structure and contains an organic carboxylic acid, at the lapse of 5 minutes since placing a 200 μL drop of water on the surface of the synthetic polymer film, a pH of an aqueous solution is less than 4, and an area equivalent circle diameter of the aqueous solution is not less than 20 mm, and at the lapse of 60 seconds since placing a drop of water on the surface of the synthetic polymer film, a static contact angle of the water drop with respect to the surface is less than 3°.

    Abstract: A method of fabricating a reactive mesogen (RM) guest-host polarizer is disclosed. The method includes forming an RM guest-host polarizer material on a substrate that promotes a substantially uniform planar alignment configuration of the RM guest-host molecules, forming a temporary layer on the RM guest-host polarizer material to align RM guest-host molecules of the RM guest-host polarizer material in the substantially uniform planar alignment configuration, performing polymerization of the RM guest-host polarizer material, and removing the temporary layer from the RM guest-host polarizer. The temporary layer includes at least one of a temporary fluid layer, a temporary particulate layer, a temporary gaseous layer, a temporary vacuum layer, and a temporary alignment substrate layer.

    Abstract: A liquid crystal display panel includes a first substrate, a second substrate, a liquid crystal layer, a first polarizing plate, and a second polarizing plate. The first substrate includes a first dielectric substrate, first and second electrodes, provided over the first dielectric substrate and configured to generate a transverse electric field in the liquid crystal layer, at least either of which has a plurality of slits, and a first alignment film placed in contact with the liquid crystal layer. The first substrate further includes an inorganic insulating layer provided between the second electrode and the first alignment film. The difference between the refractive index of the inorganic insulating layer and the refractive index of the second electrode is smaller than or equal to 0.20. The thickness of the inorganic insulating layer is greater than or equal to 50% of the thickness of the second electrode and greater than or equal to 40 nm.

    Abstract: A polarizer for use with a display device having a viewing area and a non-viewing area includes a patterned hydrophobic layer, a patterned lyotropic liquid crystal (LC) polarizer layer, a lyotropic LC polarizer alignment layer, a reactive mesogen (RM) quarter wave plate (QWP) layer, an RM QWP alignment layer, a substrate, and an adhesive. The patterned hydrophobic layer surrounds the patterned lyotropic LC polarizer layer. The patterned hydrophobic layer is wholly contained within the non-viewing area of the display device. The substrate is adjacent to the RM QWP alignment layer, and the adhesive is disposed between the substrate and the display device.

    Abstract: An endoscope distal end cover (10) is a cover for protecting a distal end (20t) of an endoscope (20) which has an observation window at the distal end, including: a synthetic polymer film (13) which is to be located over the observation window (32) when the endoscope distal end cover is attached to the distal end of the endoscope, wherein the synthetic polymer film has a surface which includes a plurality of raised portions, when viewed in a normal direction of the synthetic polymer film, a two-dimensional size of the plurality of raised portions is in the range of more than 20 nm and less than 500 nm, and a static contact angle of water with respect to the surface is not less than 150°, and a static contact angle of hexadecane with respect to the surface is not less than 60°.
