A film of the present invention is an oriented film having a light-scattering property varying with an incident angle and is useful e.g. as a viewing angle improvement film effective for improving the picture quality of a liquid crystal display device, especially for expanding the viewing angle. This oriented film is composed of a thermoplastic polymer and contains a number of micro voids participating in the above scattering property in the film. It can be produced by uniaxially drawing a film composed of a thermoplastic polymer under temperature and draw-ratio conditions to form grooves on the surface of the film perpendicular to the drawing direction.
L'invention concerne un film orienté caractérisé par le fait que le degré de diffusion de la lumière varie avec l'angle d'incidence de cette dernière. Ce film est utile pour améliorer la qualité de l'image d'un dispositif d'affichage à cristaux liquides, notamment pour améliorer l'angle de vision en l'élargissant. Le film orienté est constitué d'un polymère thermoplastique et comporte un certain nombre de pores fins qui contribuent à la caractéristique de diffusion mentionnée ci-dessus. On étire un film de polymère thermoplastique dans une seule direction, dans les conditions de température et avec un rapport d'étirage qui permettent de produire à sa surface des rainures perpendiculaires à la direction de l'étirage.
