Abstract
A liquid crystal cell comprising a pair of opposing supports one carrying a patterned electrode and the other carrying a counter electrode placed vis-a-vis with the patterned electrode and a liquid crystal material sandwiched between the two electrodes, wherein at least the patterned electrode comprises an In.sub.2 O.sub.3 coating and a remaining portion of the support where the In.sub.2 O.sub.3 coating is not disposed comprises a CeO.sub.2 coating whose refractive index is substantially equal to that of the In.sub.2 O.sub.3 coating.
