The present invention addresses the problem of providing a polymerizable liquid crystal mixture composition having excellent solubility in a solvent and excellent film-forming properties, preferably suitable for the production of a phase difference plate that exhibits reverse wavelength dispersibility and has high optical characteristics. The present invention relates to a polymerizable liquid crystal mixture composition containing at least three types of polymerizable liquid crystal compounds having different molecular structures and represented by formula (I), and containing, as the polymerizable liquid crystal compounds, polymerizable liquid crystal compounds having the same Ea and Eb in formula (I), the polymerizable liquid crystal compound having the smallest number of carbon atoms in the alkanediyl group represented by Ea and Eb among the polymerizable liquid crystal compounds is used as a polymerizable liquid crystal compound represented by formula (I-1). Polymerizable liquid crystal mixture composition containing the polymerizable liquid crystal compound (I-1), at least one polymerizable liquid crystal compound (I-2) represented by formula (I-2) defined on the basis of the structure of the polymerizable liquid crystal compound (I-1), and at least one polymerizable liquid crystal compound (I-3) defined on the basis of the structure of the polymerizable liquid crystal compound (I-1) and a polymerizable liquid crystal compound (I-3) represented by the formula.
