Claim 4

The apparatus recited in claim 1 wherein, said electrical terminals (104) have a mid-portion thereof embedded within said one of said sealing means.

Claim 5

The apparatus recited in claim 1 wherein, the interior ends of said electrical terminals within said one of said chambers are conformed to abut the surfaces of each of said pair of substrates and electrodes disposed thereon.

Claim 6

The apparatus recited in claim 4 wherein, said interior ends of said electrical terminals each has a portion thereof reversed upon itself.

Claim 7

The apparatus recited in claim 4 wherein, said interior ends of said electrical terminals have at least two portions thereof including angles of 90° or greater.

Claim 8

The apparatus recited in claim 1 wherein said electrical terminals are formed of resilient, electrically conductive material.

Claim 9

The apparatus recited in claim 1 including, a material disposed in a second (210) one of said chambers which is characterized by having certain properties thereof altered when subjected to the application of an electrical field thereto.

Claim 10

The apparatus recited in claim 8 wherein, said material comprises a glow discharge type gas.

Claim 11

The apparatus recited in claim 1 wherein, said pair of spaced apart substrates are of the same size.

Claim 12

The apparatus recited in claim 1 wherein, said pair of spaced apart substrates are both formed of glass.

Claim 13

The apparatus recited in claim 8 wherein, said material comprises a liquid crystal.

Claim 14

The apparatus recited in claim 1 wherein, said electrodes comprise transparent, electrically conductive material.

Claim 15

The apparatus recited in claim 1 wherein, said first and second sealing means are joined together.

Claim 16

A display device comprising, first and second co-extensive planar substrates, at least one of said substrates fabricated of glass and arranged to have regions of opacity and regions of transparency, electrodes formed on the adjacent surfaces of said first and second substrates in a prescribed pattern whereby an electric field can be produced between said electrodes, contact means electrically connected to said electrode means, sealing means disposed between said first and second substrates so as to provide two separate, hermetically sealed chambers between said first and second substrates, said electrodes disposed within a first one of said chambers and said contact means disposed within a second one of said chambers, and terminal means comprising an internal end, a tail portion and a mid-portion, said mid-portion is embedded in said sealing means, said tail portion extends beyond said sealing means and said coextensive substrates, said internal end extends into said second chamber, said internal end has a U-shaped portion which makes a spring-loaded electrical connection with said contact means within said second chamber.

Claim 17

A display device comprising, first and second co-extensive planar substrates, at least one of said substrates fabricated of glass and arranged to have regions of opacity and regions of transparency, electrodes formed on the adjacent surfaces of said first and second substrates in a prescribed pattern whereby an electric field can be produced between said electrodes, contact means electrically connected to said electrode means, sealing means disposed between said first and second substrates so as to provide two separate, hermetically sealed chambers between said first and second substrates, said electrodes disposed within a first one of said chambers and said contact means disposed within a second one of said chambers, and terminal means comprising an internal end, a tail portion and a mid-portion, said mid-portion is embedded in said sealing means, said tail portion extends beyond said sealing means and said coextensive substrates, said internal end extends into said second chamber, said internal end has a U-shaped portion which makes a spring-loaded electrical connection with said contact means within said second chamber.
