Abstract
The introduction of liquid-crystal material into a liquid-crystal cell is simplified by cooling the liquid-crystal material until it has a paste-like viscosity suitable for printing. After a spacer has been positioned on a first substrate, the liquid-crystal material is introduced within the interior portion of the spacer using printing techniques. A second substrate is then placed on the spacer, and the display is sealed.
Claims6
A method of manufacturing a liquid-crystal display containing liquid-crystal material between two substrates comprising:
- (a) providing a suitably prepared first substrate;
- (b) printing a predetermined two-dimensional pattern of unencapsulated liquid-crystal material having a predetermined temperature onto said first substrate, said predetermined temperature being selected to provide an optimal viscosity for printing;
- (c) covering said liquid-crystal material with a suitably prepared second substrate;
- and
- (d) sealing the region between said first and second substrates containing said two-dimensional pattern of liquid-crystal material.
