Abstract
A liquid crystal cell (40) for an electron beam-addressed liquid crystal light valve has a rigid glass substrate (16) and target substrate (44) formed of thin flexible material. The cell (40) is constructed so that the spacing between the flexible substrate (44) and the rigid substrate (16) is precisely maintained. A fixture (72) is employed for attaching the target substrate (44) to the rim (102) of the light valve body (14) prior to assembly of the cell (40).
Claims4
A liquid crystal cell mounted to an annular rim, comprising:
- (a) a flexible substrate, the edge of the flexible substrate being attached to the rim;
- (b) a rigid substrate, one surface of the rigid substrate having a substantially flat central portion and a beveled edge;
- (c) spacer means positioned between the flexible and rigid substrates for maintaining space between the flexible substrate and the central portion of the surface of the rigid substrate;
- and
- (d) bonding means for securing the beveled edge of the rigid substrate adjacent to the rim, the rigid substrate and rim being configured and arranged so that the flexible substrate is stretched when the rigid substrate is secured adjacent to the rim.
