Abstract:
1. An LCD-cell having transparent plates sealingly connected with a liquid crystal material disposed between the transparent plates, the LCD-cell comprising: a plurality of spacers interposed between the transparent plates, at least one of the spacers exhibiting a first dimension and a first material property, at least one other spacer exhibiting a second dimension different from the first dimension and a second material property different from the first material property, the plurality of spacers cooperable to define a distance between inner surfaces of the transparent plates; wherein a sum of an average value of a heated expansion of the at least one spacer perpendicular to the inner surfaces and a one to threefold variance thereof is smaller than a difference of an average value of a heated expansion of the at least one other spacer perpendicular to the inner surfaces and a one to threefold variance thereof expressed by the formula where
