Abstract:
A liquid crystal display element comprising:a first electrode structure having a first transparent substrate, a first electrode formed on said first substrate, and a first rubbed alignment layer formed on said first substrate so as to cover said first electrode; a second electrode structure having a second transparent substrate, a second electrode formed on said second substrate, and a second rubbed alignment layer formed on said second substrate so as to cover said second electrode; and a light modulating layer of an anti-ferroelectric liquid crystal material which is sandwiched between said first and second electrode substrates covered with first and second rubbed alignment layers and which has a thresholdless voltage-transmittance characteristic, wherein said first and second alignment layers are combined with said liquid crystal material so that a shifted angle between the extending direction and an optical axis of a batonnet is within Â±1 degree; and wherein said first and second rubbed alignment layers have a surface tension of 49 dyn/cm to 53 dyn/cm.
