Abstract: An optical stack for a display device includes multiple layers that are incorporated into a display device that further includes a display panel. The optical stack includes a resin layer, an alignment film, an optical compensation layer, a polarizer, and a hard coat layer that are stacked in this order from a panel side. The optical stack is formed by preparing and coating a solution for each layer, and then curing and otherwise treating each layer as warranted for a particular layer, in turn to form the optical stack.

Abstract: A synthetic polymer film is a synthetic polymer film whose surface has a plurality of raised or recessed portions. The synthetic polymer film has a crosslink structure, and the crosslink structure does not contain any nitrogen element that is a constituent of a urethane bond. The synthetic polymer film contains an organic carboxylic acid, and an amount of water required for dissolving 1 g of the organic carboxylic acid is equal to or greater than 10 mL and less than 10000 mL. 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 not more than 5, and an area equivalent circle diameter of the aqueous solution is not less than 20 mm. A synthetic polymer film whose surface has a microbicidal activity can be produced using a photocurable resin composition which contains an organic carboxylic acid or a photoacid generator which generates the organic carboxylic acid.
