Abstract
Abstract A method for fabricating a multi-domain liquid crystal display wherein adjacent areas of the display are oriented in different direction by coating the substrate with a polymer and exposing a first set of areas to ultraviolet/light from a source polarized in a first direction and then exposing a second set of areas to ultraviolet light from a source polarized in a second direction.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
122 words
A liquid crystal display having a plurality of dots arranged in a plurality of rows with a first subset of the plurality of dots being aligned in a first direction and a second subset of the plurality of dots being aligned in a second direction; a first row of the plurality of dots containing members from the first and second subsets and arranged so that no members from the same subset are adjacent; and a second row of the plurality of dots, offset from the first to provide dots arranged in a triangular configuration to produce a minimum area for color mixing, containing members from the first and second subsets and arranged so that no members from the same subset are adjacent.
Claim 2
Dependent Claim
122 words
A liquid crystal display having a plurality of dots arranged in a plurality of rows with a first subset of the plurality of dots being aligned in a first direction and a second subset of the plurality of dots being aligned in a second direction; a first row of the plurality of dots containing members from the first and second subsets and arranged so that no members from the same subset are adjacent; and a second row of the plurality of dots, offset from the first to provide dots arranged in a triangular configuration to produce a minimum area for color mixing, containing members from the first and second subsets and arranged so that no members from the same subset are adjacent.
Claim 3
Dependent Claim
15 words
Apparatus according to claim 1 wherein the first and second directions are ninety degrees apart.
Claim 4
Dependent Claim
113 words
A liquid crystal display having a substrate with a plurality of dots arranged in a plurality of rows with a first subset of the plurality of dots physically positioned in a first direction parallel to the substrate and a second subset of the plurality of dots physically positioned in a second direction parallel to the substrate; a first row of the plurality of dots containing members from the first and second subsets and arranged so that no members from the same subset are adjacent; and a second row of the plurality of dots containing members from the first and second subsets and arranged so that no members from the same subset are adjacent.
Claim 5
Dependent Claim
113 words
A liquid crystal display having a substrate with a plurality of dots arranged in a plurality of rows with a first subset of the plurality of dots physically positioned in a first direction parallel to the substrate and a second subset of the plurality of dots physically positioned in a second direction parallel to the substrate; a first row of the plurality of dots containing members from the first and second subsets and arranged so that no members from the same subset are adjacent; and a second row of the plurality of dots containing members from the first and second subsets and arranged so that no members from the same subset are adjacent.
Claim 6
Dependent Claim
30 words
Apparatus according to claim 3 wherein the second row is offset from the first to provide dots arranged in a triangular configuration to produce a minimum area for color mixing.
Claim 7
Dependent Claim
15 words
Apparatus according to claim 3 wherein the first and second directions are ninety degrees apart.
