Patent ID: 8031319

Claim:
A liquid crystal (LC) cell ( 10 ) comprising: a substrate ( 14 ) having first and second opposing surfaces; a superstrate ( 12 ) having first and second opposing surfaces and having a fill hole ( 16 ) provided therein with the fill hole having an aperture in both the first and second surfaces of said superstrate, said superstrate disposed over said substrate; a superstrate adhesion layer ( 34 ) disposed on the first surface of said superstrate about the fill hole; one or more spacers ( 24 ) disposed between said superstrate and said substrate to space apart a surface of said substrate from a surface of said superstrate; a sealant material ( 15 ) disposed on said superstrate and said substrate so as to form a cavity region ( 21 ) between said superstrate and said substrate; a liquid crystal material ( 22 ) disposed in the cavity region between said superstrate and said substrate; a cover ( 17 ) having first and second opposing surfaces with the first surface having a cover adhesion layer ( 32 ) disposed thereon and with the first surface of said cover disposed over the fill hole such that at least a portion of the first surface of said cover having the adhesion layer disposed thereon is in contact with at least a portion of the surface of said superstrate having the superstrate adhesion layer disposed thereon; and a solder material disposed between the first surface of said cover and the surface of said superstrate having the superstrate adhesion layer disposed thereon.
