Abstract

Abstract A plasma addressed liquid crystal device (LCD) and its manufacturing method is disclosed wherein a second substrate is divided into segments which are connected at a joint. A third substrate is provided which includes a plurality of barriers formed thereon. The barriers are adhered to the second substrate by a gelled paste and the joints of the second substrate overlay the barriers. The joints and the barriers are fixed by the gelled paste so as to party absorb impacts from the second substrate.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 146 words
A plasma addressed liquid crystal display comprising: a first substrate; a plurality of striped data electrodes disposed on an inner side of said first substrate; a second substrate of a predetermined thickness spaced from said first substrate to make a liquid crystal space; a third substrate spaced from said second substrate; partition barriers of a predetermined height and width positioned between said second and third substrates creating a plurality of parallel linear plasma discharge spaces and providing to said second substrate a potential for activating liquid crystal in cooperation with said data electrodes; and first and second electrodes for creating a linear discharge in each linear plasma discharge space, wherein said second substrate is composed of a plurality of substrate members which are connected to each other at selected joints, the joints overlaying and being fixed by paste on a top surface of said partition barriers.
Claim 2
Dependent Claim 146 words
A plasma addressed liquid crystal display comprising: a first substrate; a plurality of striped data electrodes disposed on an inner side of said first substrate; a second substrate of a predetermined thickness spaced from said first substrate to make a liquid crystal space; a third substrate spaced from said second substrate; partition barriers of a predetermined height and width positioned between said second and third substrates creating a plurality of parallel linear plasma discharge spaces and providing to said second substrate a potential for activating liquid crystal in cooperation with said data electrodes; and first and second electrodes for creating a linear discharge in each linear plasma discharge space, wherein said second substrate is composed of a plurality of substrate members which are connected to each other at selected joints, the joints overlaying and being fixed by paste on a top surface of said partition barriers.
Claim 3
Dependent Claim 21 words
A plasma addressed liquid crystal display as claimed in claim 1, wherein said paste comprises a gel having a predetermined elasticity.
Claim 4
Dependent Claim 52 words
A plasma addressed liquid crystal display as claimed in claim 3, wherein said first electrodes are formed on the bottom of said third substrate between said barriers, and wherein each of said barriers includes first and second segments, said second electrodes being sandwiched between the first and second segments of said barriers.
Claim 5
Dependent Claim 29 words
A plasma addressed liquid crystal display as claimed in claim 2, wherein said first and second electrodes are formed on the surface of said third substrate between said barriers.
Claim 6
Dependent Claim 52 words
