A phase compensator having a biaxial birefringent component () is fabricated by oblique deposition of an inorganic material on a base plate (). A polar angle of an evaporation path of the inorganic material is controlled in a predetermined angular range to a surface normal of the base plate (). In the oblique deposition process, the base plate () is oscillated in a horizontal direction. The phase compensator is arranged such that its slow axis (L) is perpendicular to a slow axis (L) of tilt components () in a liquid crystal panel (), and that an index ellipsoid () is tilted in an opposite direction to a tilt direction of the tilt components ().

A WORM-type recording layer in an optical information recording medium contains at least one azo-metal complex dye derived from a metal ion and a compound represented by the following general formula (1-1) or (1-2): wherein Q represents a carbocyclic group or a heterocyclic group, and Rto Rindependently represent a hydrogen atom or a substituent. The compound represented by the general formula (1-1) or (1-2) has a dissociative hydrogen atom in Q, and the dissociative hydrogen atom in Q and the hydrogen atom in the &#x2014;NH&#x2014; group marked with asterisk * are eliminated from the compound, so that the residue is bonded to the metal ion to generate the azo-metal complex dye. The azo-metal complex dye may contain a component other than the metal ion and the compound represented by the general formula (1-1) or (1-2).
