摘要：
A liquid crystal cell including: a first substrate having a first surface; a second substrate having a second surface, wherein the second surface of the second substrate is opposite and spaced apart from the first surface of the first substrate so as to define a region; and a liquid crystal material adapted to be at least partially ordered and at least one thermally reversible photochromic-dichroic compound adapted to be at least partially aligned and having an average absorption ratio greater than 2.3 in an activated state positioned within the region defined by the first surface and the second surface.
