Patent ID: 7781033

Claim:
An optical film comprising: a first layer comprising an organic compound; and a second layer comprising inorganic fine particles wherein a content of an organic compound having a molecular weight of 1000 or less of the second layer is 30% by mass or less based on a content of the inorganic fine particles of the second layer, wherein the organic compound of the first layer comprises a retardation regulating agent represented by the following Formula (1): wherein Ar 1 and Ar 3 each independently represent an aryl group or an aromatic heterocyclic group, Ar 2 represents an arylene group or a divalent aromatic heterocyclic group, L 1 and L 2 each independently represent a single bond or a divalent linking group, n represents an integer of 3 or more, Ar 2 's may be the same or different from each other, and L 2 's may be the same or different from each other, and the molecular weight of the retardation regulating agent represented by Formula (1) is 1000 or less.
