Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
237 words
A liquid crystal display device comprising a back plane member, a front plane member overlying said back plane member, a body of liquid crystal compound confined between said front and back members, one of said members including first and second spaced marginal portions respectively projecting laterally outwardly in different directions from adjacent margins of the other of said members, a plurality of electrode strips of thin substantially transparent conducting material such as indium oxide on said one of said members respectively including first portions between said members arranged in a predetermined pattern for providing a desired display, certain of said strips including lead portions extending on said first marginal portion of said one member, other of said strips including lead portions extending on said second marginal portion of said one member, a plurality of separate contact elements respectively electrically connected to said lead portions each of said contact elements including an attachment portion comprising opposed legs mechanically firmly gripping said one member therebetween with one of said legs in electrical contact with a lead portion, the mechanical gripping of said legs providing substantially the only means maintaining said electrical contact, and bodies of adhesive coating material over said first and second marginal portions and permanently securing each of said contact elements with respect to said one member, each of said contact elements including a portion projecting from said one member for electrical connection with complemenatry circuit means.

Claim 3
Dependent Claim
52 words
A liquid crystal display device, as defined in claim 1, wherein said one of said members is said back member and said front plane member has a predetermined thickness said attachment portions of the contact elements being wholly disposed beneath an imaginary projecting plane of the upper surface of said front member.
