Patent number: 9007552Abstract: A normally black liquid crystal display device includes a liquid crystal layer in which liquid crystal molecules are arranged vertically when no voltage is applied, and arranged horizontally by applying a voltage. In each of pixel regions in alignment films which are segmented in a grid by source lines and gate lines, is divided into two along a direction parallel to the source lines. The first alignment film includes a first region and a second region. The second alignment film includes a third region facing the first region and a fourth region facing the second region. In an adjacent pair of the pixel regions, pairs of the regions are adjacent to each other with corresponding one of the source lines interposed therebetween.Type: GrantFiled: June 17, 2011Date of Patent: April 14, 2015Assignee: Sharp Kabushiki KaishaInventors: Takayuki Hayano, Masayuki Tsuji, Kohji Hayashi

Patent number: 6271934Abstract: An image forming apparatus includes an image output unit for forming an image on a recording medium based on output image signals. A storage unit stores target data for reading values obtained by optically reading a gradation pattern, having a plurality of gradation levels, output by the image output unit. A correction unit corrects an image signal conversion table used to convert input image signals into the output image signals to be supplied to the signal output unit, based on reading values obtained by optically reading the gradation pattern output by the image output unit and the target data stored in the storage unit. A changing unit changes the target data.Type: GrantFiled: April 28, 1997Date of Patent: August 7, 2001Assignee: Ricoh Company, Ltd.Inventor: Kohji Hayashi
