Abstract

Provided are a transparent film that allows scenery to be observed without color unevenness in a state where light is not irradiated, a transparent screen and an image display system including the transparent film, and a transparent poster. The transparent film includes: a support; a dot array that is formed on one surface of the support and in which dots obtained by immobilizing a cholesteric liquid crystalline phase are two-dimensionally arranged; and an overcoat layer that covers the dots and is laminated on the support, in which areas of the dots and distances between the dots are made to be irregular. As a result, the object is achieved.
