摘要： The present invention provides a functional thermoplastic resin sheet including a thin film of at least one layer formed on at least one side of a thermoplastic resin sheet by a transfer method, wherein at least one layer of the thin film has functionality. The functional thermoplastic resin sheet of the first invention has a thin film of at least one layer formed on an uneven surface of a thermoplastic resin sheet having the uneven surface by a transfer method. The production process includes transferring, using a transfer film with a thin film of at least one layer formed on a surface of a base film, the thin film to an uneven surface of a thermoplastic resin sheet having the uneven surface, at which when the glass transition temperature of a thermoplastic resin sheet is denoted as Tg, a surface temperature of the thermoplastic resin sheet is in a range of not lower than (Tg−10° C.) and not higher than (Tg+70° C.), and a base film having a softening point lower than the surface temperature of the thermoplastic resin sheet is used. The transfer film uses a specific film as the base film. The light diffusion plate of the second invention is a light diffusion plate for liquid crystal displays, which has a thin film of at least one layer formed on at least one side of a thermoplastic resin sheet by a transfer method, wherein at least one layer of the thin film contains an antistatic agent. The production process includes extruding a thermoplastic resin sheet while transferring a thin film of at least one layer on at least one side of the thermoplastic resin sheet so that at least one layer of the thin film contains an antistatic agent.
