Abstract
A method for fabricating a multi-domain liquid crystal cell is disclosed, wherein first and second alignment directions are formed in first and second portions of an alignment layer provided on a substrate by selectively subjecting the first and second portions to different energy doses of linearly polarized ultraviolet light. Liquid crystal material is then injected between the one substrate and another substrate and into contact with the alignment layer, thereby obtaining a wide viewing angle in the liquid crystal device.
Claims28
A method for controlling an alignment direction in LC cell, comprising the steps of:
- subjecting a first portion of a photosensitive alignment layer formed on a substrate to a first energy dose to impart a first alignment direction in said first portion of said photosensitive alignment layer;
- and
- subjecting a second portion of said alignment layer to a second energy dose to impart a second alignment direction in said second portion of said photosensitive alignment layer.
A method for fabricating a multi-domain LC cell, comprising the steps of:
- providing a first substrate coated with a first alignment layer;
- subjecting a first region of said first alignment layer to a first energy dose of light to impart a first alignment direction;
- subjecting a second region of said first alignment layer to a second energy dose of light to impart a second alignment direction;
- providing a second substrate coated with a second alignment layer;
- positioning said first substrate adjacent said second substrate such that said first and second alignment layers face one another;
- and
- injecting LC material between said first and second substrates.
A method for storing information in a photosensitive layer comprising the steps of:
- exposing a first portion of said photosensitive layer to a first dose of radiation corresponding to a first information;
- and
- exposing a second portion of said photosensitive layer to a second dose of radiation different from said first dose and corresponding to a second information.
A method for controlling an alignment direction in LC cell, comprising the steps of:
- subjecting a photosensitive alignment layer formed on a substrate to a first energy dose to impart a first alignment direction;
- and
- subjection said photosensitive alignment layer to a second energy dose to shift the first alignment direction to a second alignment direction.
