Patent number: 5699138Abstract: A large-sized liquid crystal panel uniformly filled with a liquid crystal material may be produced through a process including the steps of: fixing a pair of substrates with a sealing member disposed therebetween to form a blank panel having an injection port, reducing a pressure within the panel, applying a liquid crystal material onto the injection port, heating the liquid crystal material to its isotropic temperature, injecting the liquid crystal material into the panel under a pressure, and filling the panel with the liquid crystal material under heating and pressurization from the injection port toward the panel inside. The pressure within the panel before the injection is reduced at a rate not exceeding 25 torr/min. The pressure for injection is increased at varying rates, e.g., with an intermediate constant pressure period.Type: GrantFiled: April 26, 1995Date of Patent: December 16, 1997Assignee: Canon Kabushiki KaishaInventors: Yasuyuki Watanabe, Kazuya Ishiwata, Masaaki Suzuki, Noriyuki Nakai, Takashi Enomoto, Naoya Nishida, Tatsuo Murata, Mutsuo Mitsui, Masayuki Shimamune

Patent number: 5546998Abstract: A smectic liquid crystal is injected into a liquid crystal panel according to the vacuum injection scheme. The liquid crystal is applied over an injection port of a blank panel while maintaining the panel at a temperature below a temperature at which the liquid crystal shows a fluidity and controlling the liquid crystal at a viscosity of 0.0005 -0.005 kg/ms. As a result, an appropriate amount of the liquid crystal can be applied, thereby providing a liquid crystal panel free from inversion of bubbles and good and uniform alignment free from alignment failure.Type: GrantFiled: February 17, 1995Date of Patent: August 20, 1996Assignee: Canon Kabushiki KaishaInventors: Masayuki Shimamune, Takashi Enomoto, Tatsuo Murata, Mutsuo Mitsui

Patent number: 5548428Abstract: A ferroelectric liquid crystal panel is prepared by injecting a ferroelectric liquid crystal into a liquid crystal panel through a process including at least four steps, i.e., a first step of reducing a pressure and evacuating gas within the liquid crystal panel, a second step of applying the ferroelectric liquid crystal to an injection port of the liquid crystal panel, a third step of causing the liquid crystal to enter into the liquid crystal panel under an increasing pressure, and a fourth step of completing injection of the liquid crystal into the liquid crystal panel under an elevated pressure. In the process, the liquid crystal panel is held at a higher temperature in the first step than in the second step. As a result, it is possible to obtain a ferroelectric liquid crystal panel which contains a ferroelectric liquid crystal at a sufficiently high packing density, free from occurrence of voids even after standing at a low temperature and has a uniform alignment state over the entire panel area.Type: GrantFiled: July 14, 1993Date of Patent: August 20, 1996Assignee: Canon Kabushiki KaishaInventors: Yuichi Masaki, Kenji Onuma, Toshifumi Yoshioka, Mutsuo Mitsui

Patent number: 5406398Abstract: A liquid crystal device is constituted by a pair of oppositely spaced substrate each having on its opposite surface a group of stripe electrodes disposed to intersect with those disposed on the other substrate, and a liquid crystal disposed between the substrates so as to be driven by a voltage applied through the stripe electrodes. The group of stripe electrodes on at least one of the pair of substrates are formed through a lithographic step including dividing the stripe electrodes into at least two divisions at a line parallel (or perpendicular) to the extension of the stripe electrodes, and repeating a pattern exposure for each division of the stripe electrodes so as to dispose a joint between the divisions of the stripe electrodes at a non-display part including a spacing between two stripe electrode on the same substrate (or at a part in alignment with a non-display part including a spacing between two stripe electrodes on the opposite substrate).Type: GrantFiled: November 4, 1993Date of Patent: April 11, 1995Assignee: Canon Kabushiki KaishaInventors: Masaaki Suzuki, Yuichi Masaki, Toshifumi Yoshioka, Mutsuo Mitsui
