Patent number: 6323922Abstract: Liquid crystal display (LCD) has sub-pixel domains in each of pixels to obtain a wide viewing angle. The sub-pixel domains are formed by divided orientation alignment in which the sub-pixel domain are subjected to rubbing in different directions opposite to each other. The liquid crystal has a splay-type TN deformation structure in the first sub-pixel domain and a normal TN deformation structure in the second sub-pixel domain. The pre-tilt angles of the liquid crystal in the first domain and second domain are selected to obtain a wide viewing angle. The LCD has a shield pattern for for shielding disclination causing afterimages and storage capacitor electrodes having a function as a signal lines.Type: GrantFiled: March 31, 2000Date of Patent: November 27, 2001Assignee: NEC CorporationInventors: Masayoshi Suzuki, Ken-Ichi Takatori, Ken Sumiyoshi, Setsuo Kaneko, Teruaki Suzuki, Hideo Shibahara, Yoshihiko Hirai

Patent number: 5550659Abstract: A liquid crystal layer is disposed between a member including a transparent substrate on which pixel electrodes, TFTs, scan lines, and data lines are formed and a member including another transparent substrate over which there are formed two sets of stripe-shaped electrodes to be vertical to each other with an insulating layer inserted therebetween and a uniform transparent conductive layer as an opposing electrode over the stripe-shaped electrodes with an insulating layer inserted therebetween. The stripe-shaped electrodes are arranged, when viewed from above, to occupy gap areas between the pixel electrodes. Sequentially applying voltage pulses to the electrodes beginning at an end portion thereof, a pen input function is achieved according to the electrostatic capacitive-coupling scheme. An active matrix liquid crystal display (AMLCD) having a pen input function is thus obtained at a low cost without deteriorating the display performance.Type: GrantFiled: July 25, 1994Date of Patent: August 27, 1996Assignee: NEC CorporationInventors: Ichiro Fujieda, Setsuo Kaneko
