Patent number: 8013972Abstract: A method of fabricating a driver circuit for use with a passive matrix or active matrix electrooptical display device such as a liquid crystal display. The driver circuit occupies less space than heretofore. A circuit (stick crystal) having a length substantially equal to the length of one side of the matrix of the display device is used as the driver circuit. The circuit is bonded to one substrate of the display device, and then the terminals of the circuit are connected with the terminals of the display device. Subsequently, the substrate of the driver circuit is removed. This makes the configuration of the circuit much simpler than the configuration of the circuit heretofore required by the TAB method or COG method, because conducting lines are not laid in a complex manner.

Patent number: 7889307Abstract: A space between substrates in a liquid crystal optical modulator can be sealed with a metal by using a simple configuration. In a seal structure between the substrates constituting a liquid crystal cell in a liquid crystal optical modulator, metal members are provided on the opposing surfaces of the two substrates, and the base metal surfaces of the metal members are brought into direct contract and joined. As a result, a low-melting metal such as a solder that has been conventionally introduced into the joint section becomes unnecessary, and a metal seal providing for strong bonding can be formed with a simple configuration. The liquid crystal optical modulator has a first substrate having a first electrode pattern including a pixel electrode, a second substrate having a second electrode pattern including a counter electrode, and a metal seal disposed so as to be sandwiched between the first substrate and the second substrate.Type: GrantFiled: March 22, 2007Date of Patent: February 15, 2011Assignee: Citizen Holdings Co., Ltd.Inventor: Masafumi Ide

Patent number: 7889306Abstract: A liquid crystal display and a method of fabricating the same is capable of strengthening adhesion between a sealant and a lower plate in a panel with a high aperture ratio to which an organic protective film is applied. The organic protective film and a gate insulating film are patterned in such a manner that the sealant comes into contact with a substrate directly. Accordingly, the organic protective film or the gate insulating film at the area coated with the sealant is partially or entirely removed to directly contact the sealant with the gate insulating film or the lower glass, thereby strengthening the adhesion between the sealant and the lower plate.Type: GrantFiled: May 19, 2000Date of Patent: February 15, 2011Assignee: LG Display Co., Ltd.Inventors: Tae Wun Ko, Sung Il Park, Dong Yeung Kwak, Gun Hee Lee, Kwang Sup Park
