Abstract
A liquid crystal display device which has a liquid crystal composition between a first substrate and a flexible second substrate. The liquid crystal composition is filled between the substrates by being dispensed on the first substrate and spread uniformly while the second substrate is being pressed against the first substrate by a roller, and the liquid crystal composition is sealed by sealing resin provided on the sides of the substrates. The gap between the substrates is maintained by spherical spacers and/or a resin structure.
Claims32
An apparatus for manufacturing a liquid crystal light modulating device including a first substrate and a second substrate, at least one of which is flexible, and a liquid crystal layer filled between the first and second substrates, said apparatus comprising:
- a support on which the first substrate is to be located;
- a dispenser which dispenses a liquid crystal material on the first substrate;
- a presser which, in cooperation with said support, presses the second substrate against the first substrate on which the liquid crystal material has been dispensed;
- and
- a mechanism which relatively moves asid presser against said support.
A method of manufacturing a liquid crystal light modulating device including a first substrate and a second substrate, at least one of which is flexible, and a liquid crystal layer filled between the first and second substrates, said method comprising the steps of:
- (a) placing the first substrate on a support and dispensing a liquid crystal material on the first substrate;
- and
- (b) placing, after the execution of the step (a), the second substrate on the first substrate and pressing the second substrate against the first substrate by relatively moving a presser against the support.
A method of manufacturing a liquid crystal light modulating device including a first substrate and a second substrate, at least one of which is flexible, a liquid crystal material filled between the first and second substrates and a seal surrounding said liquid crystal material to prevent said liquid crystal material from leaking, said method comprising the steps of:
- (a) providing the seal on at least one of said first and second substrates, the seal being incompletely hardened;
- (b) dispensing the liquid crystal material on the first substrate;
- and
- (c) placing, after the execution of the steps (a) and (b), the second substrate on the first substrate and hardening the seal to join the first and second substrates together.
A liquid crystal light modulating device comprising:
- a first substrate and a second substrate, at least one of which is flexible;
- a liquid crystal material filled between said first and second substrates;
- and
- a seal surrounding said liquid crystal material to prevent said liquid crystal material from leaking;
- wherein said liquid crystal light modulating device is manufactured by executing the steps of:
- (a) providing the seal on at least one of said first and second substrates, said seal being incompletely hardened;
- (b) dispensing the liquid crystal material on the first substrate;
- and
- (c) placing, after the execution of the steps (a) and (b), the second substrate on the first substrate and hardening the seal to join the first and second substrates together.
