Cellulose composition, optical film, retardation sheet, polarizing plate and liquid crystal display device

A cellulose composition, comprising:

• at least one kind of cellulose compound;
• at least one kind of compound represented by formula (I);
• and
• at least one kind of low molecular weight compound (A);
• wherein molecular absorption wavelength of the low molecular weight compound (A) derived from an electric dipole transition moment My in a direction approximately orthogonal to a molecular long axis direction, is longer than that derived from an electric dipole transition moment Mx in a direction approximately parallel to the molecular long axis direction;
• and
• wherein magnitude of the electric dipole transition moment |My| of the low molecular weight compound (A) in the direction approximately orthogonal to the molecular long axis is larger than that of the electric dipole transition moment |Mx| in the direction approximately parallel to the molecular long axis direction:
• wherein L1, L2, L3, and L4 each independently represent a single bond, or a divalent linking group selected from the group consisting of —O—, —CO—, —NRA— (RA represents an alkyl group having 1 to 7 carbon atoms or a hydrogen atom), —CH2— and a combination of these;
• Y1 and Y2 each independently represent an alkyl group;
• Ra, Rb and Rc each independently represent a substituent;
• m represents an integer of 0 to 4;
• t represents an integer of 1 or 2;
• and m11 and m12 each independently represent an integer of 0 to 10.
