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.
Claims28
A method of manufacturing a liquid crystal modulating device including a first substrate and a second substrate, at least one of which is flexible, a liquid crystal layer filled between the first and second substrates, and a sealing material for preventing the liquid crystal material from leaking, said method comprising the steps of:
- (a) providing the sealing material on at least one of the first and second substrates;
- (b) dispensing a liquid crystal material onto the first substrate;
- (c) pressing the second substrate toward the first substrate from a leading edge thereof thereby preliminarily laminating the first and second substrates;
- and
- (d) pressing the first and second substrates while heating the sealing material thereby bonding the first and second substrates with each other by the sealing material.
A manufacturing apparatus for manufacturing a liquid crystal modulating device including a first substrate and a second substrate, at least one of which is flexible, a liquid crystal layer filled between the first and second substrates, and a sealing material for preventing the liquid crystal material from leaking, said manufacturing apparatus comprising:
- a first station for providing the sealing material on at least one of the first and second substrates;
- a second station for dispensing a liquid crystal material onto the first substrate;
- a third station for pressing the second substrate toward the first substrate from a leading edge thereof thereby preliminarily laminating the first and second substrates;
- and
- a fourth station for pressing the first and second substrates toward each other while heating the sealing material thereby bonding the first and second substrates with each other by the sealing material.
