Abstract: A gas separation membrane includes a porous layer, a first resin layer provided at a surface on one side of the porous layer, the first resin layer including an organopolysiloxane, and a second resin layer provided at a surface of the first resin layer on a side opposite to that of the porous layer, the second resin layer including an organopolysiloxane. The first resin layer has a porosity greater than that of the second resin layer. The second resin layer is chemically bonded to the first resin layer.

Abstract: A flow passage forming member includes flow passage forming member main bodies 140 and 146 that are formed of a resin material and define at least a part of a flow passage, a metal protective film 200 that is provided on a surface of the flow passage forming member main body 140 and a surface of the flow passage forming member main body 146 defining at least the flow passage and is formed of a metal material, and a protective film 210 that is laminated on the metal protective film 200 and contains an oxide or a nitride of at least on element selected from the group consisting of tantalum (Ta), titanium (Ti), zirconium (Zr), niobium (bib), vanadium (V), hafnium (Hf), silicon (Si), aluminum (Al), tungsten (W), and yttrium (Y).

Abstract: A phase difference compensation film formed of a polycarbonate, which can be used in a liquid crystal display and which shows a decreased change in retardation caused by a temperature change at a stretch forming time due to the use of a polycarbonate having a branched structure and having a viscosity-average molecular weight of 40,000 or less as the above polycarbonate.
