  • Patent number: 6226064
    Abstract: It is an object of the invention to provide a liquid crystal display apparatus produced by combining a negative dielectric constant anisotropy and a perpendicular orientation film, the apparatus capable of preventing lowering of contrast because of a phase difference due to a tilt of liquid crystal molecules at the time of non-select voltage application and ensuring both high luminance and high contrast. The liquid crystal display apparatus produced by combining the negative dielectric constant anisotropy and the perpendicular orientation film is used in the normally black mode, and a phase difference plate for compensating the phase difference caused by the tilt of the liquid crystal molecules at the time of non-select voltage application is provided so as to be adjacent to a liquid crystal cell, with the result that light-transmittance at the time of non-select voltage application can be kept in a low value and contrast can be largely improved.

  • Patent number: 6119902
    Abstract: A liquid jet pump constructed to suck a liquid within a container on which the pump is mounted and jet the liquid out of a nozzle by pushing down the head of the pump. The nozzle is so formed so as to ascend forward obliquely, and is provided with a discharge valve housing a ball-like valve for closing a valve seat provided at an proximal edge within the nozzle. The valve member is movable both back and forth within the nozzle to keep the liquid from dripping of the nozzle.

  • Patent number: 6031593
    Abstract: On the first substrate that serves as an active-element-side substrate, pixel electrodes are formed with a flattening film interpolated in between. On the second substrate that serves as an opposing-side substrate, light-shielding films are formed into an island pattern which allows the light-shielding films to shield the respective active elements on the first-substrate side from light, and gap-controlling sections are formed into the same island pattern as the light-shielding films by exposing positive-working photosensitive resin layer that has been applied onto the entire surface of the second substrate from the back-surface side of the second substrate by using the light-shielding films as a photomask. The flattening film makes it possible to suppress the occurrence of disclination in the liquid crystal molecules. Therefore, the light-shielding films can be formed as the island pattern that only shield the active elements from light, and consequently it is possible to improve the aperture rate.
