Patent number: 7502083Abstract: On a first substrate are formed a TFT provided to each pixel, an insulating film which covers the TFT, and a reflective layer which is provided on the insulating film so as to be insulated from the TFT and reflects light incident from a second substrate side. The reflective layer is covered with a passivation film on which a first electrode made of a transparent conductive material, such as ITO having the work function equivalent to a second electrode, is formed and connected to the TFT. The passivation film covering the reflective layer prevents the reflective surface of the reflective layer from deteriorating in reflection properties during a process for connecting the TFT and the first electrode. Further, the first and second electrodes having similar characteristics can symmetrically AC drive the liquid crystal layer.Type: GrantFiled: July 17, 2007Date of Patent: March 10, 2009Assignee: Sanyo Electric Co., Ltd.Inventors: Nobuhiko Oda, Satoshi Ishida, Tsutomu Yamada

Patent number: 7482746Abstract: A reflective layer for reflecting light incident from a second substrate side and transmitting through a second electrode made of ITO or the like is formed above a first substrate, a switching element provided for each pixel, and an insulating film covering the switching element, the reflective layer being insulated from the switching element. A first electrode having a work function similar to the second electrode and made of a transparent conductive material such as ITO is formed more proximate to a liquid crystal layer than is the reflective layer and is connected to the switching element. The thickness of the first electrode is set to 100 ? or less or in a range approximately from 750 ? to 1250 ?. Alternatively, the switching element maybe connected to the reflective electrode, the first electrode and the reflective electrode which are formed with an insulating film therebetween may be capacitively coupled, and the first electrode may be driven by the reflective electrode via the capacitor.Type: GrantFiled: September 18, 2006Date of Patent: January 27, 2009Assignee: Sanyo Electric Co., Ltd.Inventors: Shinji Ogawa, Kazuhiro Inoue, Norio Koma, Nobuhiko Oda, Satoshi Ishida, Tsutomu Yamada, Tohru Yamashita

Patent number: 7163850Abstract: In a bottom gate-type thin-film transistor manufacturing method, after ion doping, an ion stopper (55) is removed. The ion stopper (55) does not remain in the interlayer insulating film (8) lying immediately above the gate electrode. The thin-film transistor has such a structure that no ion stopper (55), and the interlayer insulating layer is in direct contact with at least the channel region of the semiconductor layer (4). The impurity concentration in the vicinity of the interface between the interlayer insulating film and the semiconductor layer 4 is 1018 atoms/cc or less. This structure can prevent the back channel phenomenon and reduce variations in characteristic resulting from variations in manufacturing.Type: GrantFiled: September 20, 2004Date of Patent: January 16, 2007Assignee: Sanyo Electric Co., Ltd.Inventors: Nobuhiko Oda, Toshifumi Yamaji, Shiro Nakanishi, Yoshihiro Morimoto, Kiyoshi Yoneda
