Abstract

Abstract A liquid crystal device comprising a pair of substrates each having an electrode, and a liquid crystal layer having a chiral smectic phase, provided between the substrates, wherein a first substrate which is one of the substrates comprises; i) a plurality of first electrodes dividedly disposed, the plurality of first electrodes being covered with a monomolecular film or monomolecular built-up film in such a way that the monomolecular film or monomolecular built-up film provided on the first electrodes and between the first electrodes is formed in a continuous film; and ii) a second electrode provided on the monomolecular film or monomolecular built-up film in such a way that an MIM device is formed at the part where the first electrodes, the monomolecular film or monomolecular built-up film and the second electrode overlap in layers.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 122 words
A liquid crystal device, comprising: a pair of substrates, either having a plurality of electrodes including picture element electrodes and a liquid crystal layer having a chiral smectic phase provided between said substrates, wherein a first substrate of said pair of substrates comprises: (i) a plurality of first electrodes dividedly disposed to partially overlap said picture element electrodes, said plurality of first electrodes being covered with a continuous monomolecular or monomolecular built-up film; and (ii) a plurality of second electrodes provided on said continuous monomolecular or monomolecular built-up film in areas other than over said picture element electrode such that a MIM device is formed where said first electrodes, said monomolecular or monomolecular built-up film and said second electrodes overlap in layers.
Claim 2
Dependent Claim 122 words
A liquid crystal device, comprising: a pair of substrates, either having a plurality of electrodes including picture element electrodes and a liquid crystal layer having a chiral smectic phase provided between said substrates, wherein a first substrate of said pair of substrates comprises: (i) a plurality of first electrodes dividedly disposed to partially overlap said picture element electrodes, said plurality of first electrodes being covered with a continuous monomolecular or monomolecular built-up film; and (ii) a plurality of second electrodes provided on said continuous monomolecular or monomolecular built-up film in areas other than over said picture element electrode such that a MIM device is formed where said first electrodes, said monomolecular or monomolecular built-up film and said second electrodes overlap in layers.
Claim 3
Dependent Claim 29 words
A liquid crystal device according to claim 1, wherein an aligning film is further provided on said monomolecular film or monomolecular built-up film and said plurality of second electrodes.
Claim 4
Dependent Claim 25 words
A liquid crystal device according to claim 1, wherein said monomolecular film or monomolecular built-up film formed has been obliquely irradiated with an ion beam.
Claim 5
Dependent Claim 18 words
