Abstract
The display area of a liquid crystal display cell is increased by placing conductive epoxy within the boundary which seals the liquid crystal to connect the top glass plate with the bottom glass plate, in contrast with the conventional method of making the electrical connection outside the display area. The conductive epoxy is dispensed in areas not occupied by the liquid crystal patterns. The conductive epoxy can be in the form of particles of spheres or rods serving as spacers for maintaining the gap dimension between the two glass plates. The conductive epoxy can also be integrated with the boundary sealing epoxy or fill a notch cut in the boundary sealing epoxy.
Claims6
A method of fabricating a liquid crystal cell having a top glass plate and a bottom glass plate for sandwiching liquid crystals, comprising the steps of:
- applying sealing adhesive for a seal surrounding said liquid crsytals,
- depositing alignment films on said glass plate and said bottom glass plate,
- aligning said alignment films on said top glass plate and said bottom glass plate,
- dispersing spacer particles on said bottom plate,
- compressing said spacer particles to form a continuous pattern connecting said top glass plate with said bottom glass plate,
- cutting a notch in said seal, and
- filling said notch with epoxy having conducting particles which functions as a part of said seal.
