Abstract
Abstract A photosensitive recording member is disposed above a twisted nematic field effect mode liquid crystal display cell for recording a light image formed by the twisted nematic field effect mode liquid crystal display cell. At least one of substrates which confronts the photosensitive recording member is made of a fiber plate including a plurality of optical fibers of which axes are perpendicular to the plane of a liquid crystal layer of the twisted nematic field effect mode liquid crystal display cell.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
105 words
A liquid crystal display and record system comprising: first and second opposing substrates, said first substrate including a plurality of optical fibers, the axes of which are perpendicular to the plane of said first substrate; liquid crystal material sandwiched between said first and second opposing substrates; a first polarizer substantially juxtaposed to and above said first substrate; a second polarizer disposed below said second substrate; a photosensitive recording member substantially juxtaposed to said first polarizer; and a shutter means disposed above said photosensitive recording member, said shutter means and said photosensitive recording member both being removably secured to the liquid crystal display and record system.
Claim 2
Dependent Claim
105 words
A liquid crystal display and record system comprising: first and second opposing substrates, said first substrate including a plurality of optical fibers, the axes of which are perpendicular to the plane of said first substrate; liquid crystal material sandwiched between said first and second opposing substrates; a first polarizer substantially juxtaposed to and above said first substrate; a second polarizer disposed below said second substrate; a photosensitive recording member substantially juxtaposed to said first polarizer; and a shutter means disposed above said photosensitive recording member, said shutter means and said photosensitive recording member both being removably secured to the liquid crystal display and record system.
Claim 3
Dependent Claim
22 words
A liquid crystal display and record system as in claim 1, wherein an illumination light source is disposed below said second polarizer.
Claim 4
Dependent Claim
25 words
A liquid crystal display and record system as in claim 1, wherein a scattering plate is disposed between said light source and said second polarizer.
