Abstract
The cell comprises two spaced apart substrates and a plurality of terminals for the cell disposed along an exposed surface of one of the substrates. Electrodes are disposed on each of the substrates, and connector means for connecting one of the terminals on the one substrate and an electrode on the other substrate comprises a fused glass bump bridging the space between the two substrates and electrically connected to the one terminal and the electrode on the other substrate. The glass bump contains metal particles dispersed therethroughout to provide it with electrical conductive characteristics.
Claims4
In a method of fabricating a liquid crystal cell, the improvement comprising:
- providing on a surface of a first glass substrate first and second spaced apart conductive layers,
- adhering to a portion of said first layer a slurry of glass in the form of a bump, said slurry having conductive particles therewithin,
- providing on a surface of a second glass substrate a third conductive layer,
- disposing said two substrates in face-to-face spaced apart relation with said second and third layers disposed in overlapped relation and with said bump disposed in alignment with a portion of said third layer, and
- simultaneously fusion bonding said bump to said first and third layers while maintaining a space between said substrates, said bump providing an electrical connection between said first and third layers and spanning the space between said substrates.
