Patent number: 7518667Abstract: In a provided LCD device, a common electrode and a picture element electrode which make up the main portion of a unit picture element of the LCD device are both made up of one thin conductive layer made of a Cr layer, while a common electrode wiring line and a data line or a like which are connected to the common electrode and the picture element electrode respectively are each formed as a stacked film made up of a first conductive film (thick Cr layer) and a second conductive film (thin Cr layer). This configuration enables increasing the film thickness of wiring lines such as, especially, the common electrode wiring line and the data line or the like, thus decreasing a wiring line resistance thereof.Type: GrantFiled: August 1, 2005Date of Patent: April 14, 2009Assignee: NEC LCD Technologies, Ltd.Inventors: Takuya Asai, Syouichi Kuroha, Takeshi Sasaki

Patent number: 6888601Abstract: In a lateral electric field liquid crystal display device, a major electrode portion for generating a lateral electric field is formed using a layer different from a layer on which other electrodes and lines are formed. In this case, the major portion is formed to have a thickness of {fraction (1/20)} to ? of the thickness of each of the other electrodes and lines. Thus, flatness of a base film of an alignment layer is significantly improved, also alignment layer material can be coated and formed with high flatness on the base film, and rubbing of the alignment layer material can be performed uniformly for the overall substrate surface.Type: GrantFiled: January 29, 2003Date of Patent: May 3, 2005Assignee: NEC LCD Technologies, Ltd.Inventors: Takuya Asai, Syouichi Kuroha, Takeshi Sasaki

Patent number: 6618109Abstract: A liquid crystal display apparatus has a pair of substrates opposing to each other and a liquid crystals sandwiched between the pair of substrates. One side of substrate is provided with gate lines and signal lines which approximately cross each other. TFTs are provided close to intersection portion of the gate line and the signal line. Pixel electrodes and common electrodes are provided at each pixel enclosed by the gate line and the signal line. Each of pixel electrodes and common electrodes has bent points more than one and is alternately formed in parallel with each other. Both the pixel electrode and the common electrode are made up of bent sections and projected sections projecting toward concave sections of opposite electrodes from convex side top sections of the bent sections.Type: GrantFiled: July 27, 2001Date of Patent: September 9, 2003Assignee: NEC LCD Technologies, Ltd.Inventors: Masanobu Hidehira, Makoto Watanabe, Syouichi Kuroha

Publication number: 20030142259Abstract: In a lateral electric field liquid crystal display device, a major electrode portion for generating a lateral electric field is formed using a layer different from a layer on which other electrodes and lines are formed. In this case, the major portion is formed to have a thickness of {fraction (1/20)} to ⅓ of the thickness of each of the other electrodes and lines. Thus, flatness of a base film of an alignment layer is significantly improved, also alignment layer material can be coated and formed with high flatness on the base film, and rubbing of the alignment layer material can be performed uniformly for the overall substrate surface.Type: ApplicationFiled: January 29, 2003Publication date: July 31, 2003Applicant: NEC CorporationInventors: Takuya Asai, Syouichi Kuroha, Takeshi Sasaki
