Abstract
Electroluminescent (EL) behavior has been evaluated in a cell which contain ed molecular dispersion of 1,4-bis(N,N-diphenylaminophenyl-1,3,4-oxadiazoly l)benzene (OXD) in a low-molecularweight liquid crystal, 4-octyloxy-4'-cyan obiphenyl (8OCB). EL emission was observed above the temperature where the OXD/8OCB mixture showed a liquid-crystalline phase. Furthermore, we fabrica ted an EL device which consisted of interdigital electrodes coated onto a g lass substrate. It was found that the EL emission from the device was highl y polarized.
