1. A transparent film comprising:
- a support;
a dot array that is formed on one main 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 dot array and is laminated on the support,wherein in a case where, in a cumulative distribution diagram in which a horizontal axis represents an area of the dots, an area of the dots corresponding to a cumulative distribution of 50% is represented by Xs, an area of the dots corresponding to a cumulative distribution of 5% is represented by Ysa, and an area of the dots corresponding to a cumulative distribution of 95% is represented by Ysb, andin a case where, in a cumulative distribution diagram in which a horizontal axis represents an inter-dot distance as a distance between one dot and another dot that is most adjacent to the dot, an inter-dot distance corresponding to a cumulative distribution of 50% is represented by Xd, an inter-dot distance corresponding to a cumulative distribution of 5% is represented by Yda, and an inter-dot distance corresponding to a cumulative distribution of 95% is represented by Ydb, the dot array satisfies at least one of the following Expression (1), (2), (3), or (4),

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.
