Abstract

The present invention is intended to provide a transparent film containing a transparent material and a glass fiber substrate with a high transparency, a high surface smoothness and a reduced retardation. This transparent film in the present invention comprises the transparent material made of a transparent resin, and the glass fiber substrate made of glass fiber having latitudinal yarns and longitudinal yarns. In this transparent film, at least one of the latitudinal yarn and the longitudinal yarn of the glass fiber has 0.3 twists or less per inch. This invention enables it to provide a transparent film with a high transparency, a high a surface smoothness, a minimized retardation while retaining its reduced thermal expansion coefficient. In addition, this transparent film is enabled to exhibit superior performances in terms of thermal resistance, surface hardness, gas barrier property and so on.
