  • Patent number: 6239855
    Abstract: A method for producing a liquid crystal display panel of the present invention includes the steps of: forming a plurality of injection seals on at least one of a pair of substrates, the injection seals defining a liquid crystal injection area; forming a dummy seal of dispersed sealant particles outside the liquid crystal injection area; attaching the substrates to each other thereby sandwiching the injection seal and the dummy seal therebetween; and injecting a liquid crystal material into the liquid crystal injection area formed between the pair of substrates.

  • Patent number: 6104467
    Abstract: A cell gap uniformity in the vicinity of a seal and inside a display region of a liquid crystal display device is enhanced. Further, even when a multi-daylight press is used in a substrate bonding process, a variation in cell gap depending on the stratal positions of substrates is suppressed. In the process of bonding together two substrates on which display use electrodes are formed, the two substrates are bonded together with interposition of a seal member and a spacer. Thereafter, first, the bonded substrates are pressurized according to a specified pressurization profile in a normal temperature state of, for example, 26.degree. C., thereby extending the seal member. Subsequently, these substrates are pressurized according to a pressurization profile whose maximum pressure is set smaller than the maximum pressure in the normal temperature state with heat applied to the substrates, thereby hardening the seal member.

  • Patent number: 5982470
    Abstract: A liquid crystal display device includes a pair of substrates having a plurality of display-use electrodes formed thereon, a seal for connecting the pair of substrates in such a manner that respective electrode forming surfaces face each other, a liquid crystal layer formed by sealing a liquid crystal in a space surrounded by the pair of substrates and the seal, and dummy electrodes for achieving a uniform thickness of the liquid crystal layer in the display area. The display-use electrodes and the dummy electrodes are interleaved on four sides of the seal, and an absolute value for variations in interleaved ratio in the four sides, indicative of a ratio of an area occupied by the display-use electrodes and the dummy electrodes on the seal is not more than a predetermined value.

  • Patent number: 5879497
    Abstract: An alignment device for aligning a liquid crystal display device-use substrate is a rubbing device provided with a rubbing roller, the rubbing roller being composed of a rotary roller and a rubbing cloth, the rubbing cloth being provided around the circumferential surface of the rotary roller. The rubbing device carries out alignment by rotating the rubbing roller so as to rub an alignment film formed on the surface of the liquid crystal display device-use substrate, in a specific direction with piles provided on the rubbing cloth. One of the directions of the pile lines of the rubbing roller provided around the rotary roller is tilted to the rotation direction of the rotary roller.

  • Patent number: 4803088
    Abstract: The present invention relates to a container packed with instant food to be cooked by a microwave oven which allows a solid instant food such as instant chow mein and instant macaroni to be reconstituted to its original cooked state with good texture in a short period of time when the food is cooked in a microwave oven without the need to drain water after it is cooked.The container packed with instant food comprises: a container composed of a container body and a lid which is capable of tightly or substantially tightly sealing said container; and a solid instant food accommodated in said container, wherein said food is to be reconstituted and made ready for eating on absorbing water when said container packed with said food is heated in a microwave oven after water is added thereto in an amount equivalent to between 100 and 155 wt % of the water absorption capacity of said food.
