Abstract

A liquid crystal display device having a liquid crystal composition, requiring neither an alignment film nor alignment treatment on a substrate. The problem is solved by a low molecular weight polar compound for homogeneously aligning a liquid crystal medium relative to the substrate, for example, the low molecular weight polar compound represented by formula (1).Formula 95M-P  (1) In formula (1), M is a nonpolar group having 1 or more carbons, and P is a polar group.
