FABRICATION OF LIQUID CRYSTAL DEVICES
First Claim
Patent Images
1. A process for filling a liquid crystal device container with liquid crystal material comprising:
- flowing said liquid crystal material through an opening in said container and into said container, and altering the flow path of said liquid crystal material within said container to cause a repeated contacting of the interior surfaces of said container by said material flowing across said surfaces in different directions.

Abstract
During device filling, as by flowing the liquid crystal material through ports opening into opposite ends of the device, the walls of the device are caused to alternately outwardly bow and inwardly collapse to cause variations in the paths of flow of the material through the device.

2. A process for fabricating a liquid crystal device of the type comprising a container and a liquid crystal material therewithin, said method comprising:
- flowing the liquid crystal material through said container, and simultaneously with said flowing step, alternately enlarging and reducing the volume of two regions of said container relative to one another for alternating the preferred flow path of said liquid crystal material from region to region.
-
3. The process as in claim 2, wherein a wall portion of said container is alternately inwardly and outwardly bowed.
-
4. The process as in claim 2, wherein the direction of flow of said material is reversed at least once during said process.
-
5. A process for fabricating a liquid crystal device of the type comprising a container and a liquid crystal material therewithin, said method comprising:
- providing two extending tubulations each having an end opening within said container in sealed relation therewith, immersing thE opposite end of one of said tubulations in a first body of liquid crystal material, exhausting said container through the other of said tubulations, thereby causing flow of said material from said first body through said cell, and alternately with said exhausting step, immersing the opposite end of said other tubulation in a second body of liquid crystal material and applying pressure against said second body for causing flow of said material from said second body through said cell.
