Patent number: 7480027Abstract: A method of manufacturing a liquid crystal display device by sealing liquid crystals between the substrates relying upon a drop-injection method making it easy to determine a suitable dropping amount of the liquid crystals. The method comprises forming pillar spacers for maintaining a cell thickness on a CF substrate, measuring the height of the pillar spacers, determining the dropping amount of the liquid crystals based on the number of times of executing a step of forming an alignment film again effected for the CF substrate after measuring the height of the pillar spacers, dropping the liquid crystals in the determined dropping amount onto the CF substrate or onto a TFT substrate, sticking the CF substrate and the TFT substrates together in vacuum, and returning the pressure back to the atmospheric pressure to inject the liquid crystals into between the two substrates.Type: GrantFiled: March 18, 2005Date of Patent: January 20, 2009Assignee: Sharp Kabushiki KaishaInventors: Hiroyasu Inoue, Minoru Otani, Yuji Nakahata, Satoshi Murata, Norimichi Nakayama, Hiroyuki Sugimura

Patent number: 7316750Abstract: The present invention relates to a method for manufacturing a liquid crystal display utilizing the dispense-injection method, and it is an object of the invention to provide a method for manufacturing a liquid crystal display which allows an optimum quantity of liquid crystals to be dispensed on each substrate. At a dispense-injection step, in the case of a two-shot process for fabricating two liquid crystal display panels from a single glass substrate 80, the heights of support posts on two CF substrates 82 (let us call them surfaces A and B) having columnar spacers formed thereon are measured at a plurality of points (e.g., five locations indicated by numerals 1 through 5) on each of the surfaces A and B using a laser displacement gauge and an average value of the height is obtained. The support post height of the columnar spacers is thus measured in advance to control the quantity of dispensed liquid crystals based on the measured value.Type: GrantFiled: October 6, 2004Date of Patent: January 8, 2008Assignee: Sharp Kabushiki KaishaInventors: Satoshi Murata, Hiroyuki Sugimura, Norimichi Nakayama, Hiroyasu Inoue

Patent number: 7202933Abstract: A liquid crystal display device has a liquid crystal inserted between first and second substrates and surrounded by a peripheral seal. The liquid crystal is dripped onto the first substrate in an area defined by the seal of the first substrate. The first substrate and the second substrate are joined or bonded together under pressure in a vacuum chamber. The chamber is then exposed to the atmosphere while keeping the first substrate and the second substrate under pressure. The pressure is then released and thereafter light is irradiated onto the peripheral seal. The vacuum chamber includes upper and lower surface plates to support the substrates. The surface plate includes an electrostatic chuck and a vacuum attraction passage provided in the chuck.Type: GrantFiled: September 17, 2004Date of Patent: April 10, 2007Assignee: Sharp Kabushiki KaishaInventors: Satoshi Murata, Hiroyuki Sugimura, Norimichi Nakayama
