Abstract
A method for fabricating a liquid crystal cell and related device includes providing an alignment layer of a light sensitive material on a substrate; and exposing the alighment layer to unpolarized or partially polarized light, to provide pretilt for the molecules of the alighment layer.
Claims23
A method of manufacturing a liquid crystal display device, comprising:
- providing an alignment layer on a substrate;
- and
- exposing said alignment layer to light obliquely incident onto a surface of said alignment layer to form a pretilt angle, the exposing step simultaneously selecting a direction of the pretilt angle and an amount of the pretilt angle.
A method of manufacturing a liquid crystal display device, comprising:
- providing an alignment layer on a substrate;
- exposing said alignment layer to light obliquely incident onto a surface of said alignment layer, the exposing step comprising:
- exposing a first portion of the alignment layer to said light obliquely incident onto the surface of the alignment layer;
- and
- exposing a second portion of the alignment layer to said light obliquely incident onto the surface of the alignment layer, said first and second portions being different from one another;
- and
- providing a liquid crystal material adjacent each of said exposed first and second portions of the alignment layer, the liquid crystal material adjacent the first portion of the alignment layer having a first pretilt and the liquid crystal material adjacent the second portion of the alignment layer having a second pretilt different than said first pretilt.
A method of manufacturing a liquid crystal display device, comprising:
- providing an alignment layer on a substrate;
- exposing said alignment layer to light obliquely incident onto a surface of said alignment layer, the exposing step comprising:
- exposing a first portion of the alignment layer to said light obliquely incident onto the surface of the alignment layer;
- and
- exposing a second portion of the alignment layer to said light obliquely incident onto the surface of the alignment layer, said first and second portions being different from one another;
- and
- providing a liquid crystal material adjacent a respective one of said exposed first and second portions of the alignment layer, the liquid crystal material adjacent the first portion of the alignment layer having a first pretilt and the liquid crystal material adjacent the second portion of the alignment layer having a second pretilt substantially perpendicular to said first pretilt.
A method of manufacturing a liquid crystal display device, comprising:
- providing an alignment layer on a substrate;
- exposing said alignment layer only once to light obliquely incident onto a surface of said alignment layer to form a pretilt angle, the exposing step simultaneously selecting a direction of the pretilt angle and an amount of the pretilt angle;
- and
- providing a liquid crystal material adjacent the alignment layer.
