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 95 M-P (1) In formula (1), M is a nonpolar group having 1 or more carbons, and P is a polar group.
Claims15
A liquid crystal display device, comprising:
- a pair of transparent substrates, wherein the pair of transparent substrates are facing each other;
- a transparent electrode formed on at least one of surfaces facing each other of the pair of transparent substrates;
- and
- a liquid crystal medium sealed between the pair of transparent substrates and containing a low molecular weight polar compound,
- with the proviso that the liquid crystal display device does not contain an alignment film and where alignment treatment is not applied.
