  A composition includes at least one organic compound of a first type of the general formula I and at least one organic compound of a second type of the general structural formula II, wherein Core in formula I is a conjugated organic unit capable of forming a rigid rod-like macromolecule, Gk is a set of ionogenic side-groups providing solubility of the organic compound of the first type in a solvent and give rigidity to the rod-like macromolecule; and wherein Sys in formula II is an at least partially conjugated substantially planar polycyclic molecular system capable of forming board-like supramolecules via π-π-interaction, and X, Y, Z and Q are substituents. The composition is capable of forming a lyotropic liquid crystal solution, which can form a solid retardation layer of biaxial type substantially transparent to electromagnetic radiation in the visible spectral range. The type and degree of biaxiality of the said optical retardation layer is controlled by a molar ratio of the organic compounds of the first and the second type in the composition. An optical film comprising a solid retardation layer formed of the composition, a method of producing the optical film, and a vertical alignment liquid crystal display using said retardation layer are also provided.
