摘要:
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. In the filling step, a portion of the liquid crystal material near the injection port is held in its isotropic phase and the liquid crystal material except for the portion is transformed at least once into a smectic phase.

A color filter plate suitable for inclusion in a color liquid crystal display panel is produced through a process including the steps of (a) forming a color filter pattern on a transparent substrate, (b) forming a light-interrupting mask layer over the color filter pattern, (c) abrading the mask layer with an abrasive to expose the color filter pattern and leave a patterned mask layer contiguous with the color filter pattern, and (d) coating the color filter pattern and the patterned mask layer with a protective layer. As a result, it becomes possible to omit a step of patterning the mask layer and an exposure mask for the patterning, so that the process is simplified, the production cost is lowered and the latitude of the mask-forming material is increased.
摘要:
A liquid crystal device is formed of a pair of substrates oppositely disposed with adhesive particles dispersed between the substrates, a sealing member disposed along a periphery of the substrates while leaving a liquid crystal injection port to be later sealed, and a liquid crystal disposed in a region surrounded by the sealing member and the liquid crystal injection port later sealed. In the device, the region surrounded by the sealing member for disposing the liquid crystal is divided into a rectangular first region for effective optical modulation and a second region surrounding the first region not contributing to substantial optical modulation, and the adhesive particles are disposed in a dispersed state in the first region and selectively at a portion of the second region in proximity to the injection port so as to minimize a cell gap distribution and provide a broader drive margin temperature characteristic.

A color filter is produced through the steps of: forming a layer of a color filter material including a colorant dispersed in a photosensitive resin on a substrate; and pre-baking, exposing and developing the color filter material layer to leave a color filter pattern on the substrate. In the developing step, a developer liquid is applied in the form of a curtain onto the exposed color filter material layer on the substrate, the substrate is allowed to stand in a substantially still state and then the substrate is supplied with an ultrasonic wave projected perpendicularly to the substrate while being in contact with the developer liquid. The ultrasonic wave is preferably uniformized by at least two rotating reflection or diffusion plates before it is projected onto the substrate. As a result, the color filter pattern can be developed with little development irregularity even on a large-size substrate.

A method for manufacturing an electronic substrate structure comprising a substrate, a glass layer, and a conductive layer. This method may include the steps of arranging the glass layer on the substrate, arranging the conductive layer that includes a precious metal particle on the glass layer while directly contacting the glass layer, and heating the glass layer together with the conductive layer at a temperature that is lower than a softening point of the glass layer so that the particle is put into the glass layer. The particle has a diameter of not less than 1 μm and not more than 10 μm.
