Abstract

The inventors have intensively studied and found that an electrostatic indicator that can visualize the magnitude of its charge potential can be provided by using a liquid crystal composition and forming multiple regions in which the alignment of the molecules of the liquid crystal composition differently changes in response to electric potential. Furthermore, there is provided an electrostatic indicator that can be placed in a two-dimensional or three-dimensional manner to also visualize spatial distribution of high or low charge potential.
