Patent number: 7880854Abstract: A liquid crystal display panel includes a TFT substrate, a color filter (CF) substrate opposed to the TFT substrate, a sealant disposed between the TFT substrate and the CF substrate and disposed between portions of both the substrates located immediately outside display regions thereof, and a liquid crystal layer disposed between the TFT substrate and the CF substrate. The CF substrate is provided with a light-shielding layer at a portion located immediately outside its display region. The light-shielding layer is provided with a slit at a region that coincides with a line on the TFT substrate.Type: GrantFiled: March 20, 2006Date of Patent: February 1, 2011Assignee: Sharp Kabushiki KaishaInventors: Masahiko Kondo, Shingo Jogan

Patent number: 7839473Abstract: In a multi-gap semi-transmissive liquid crystal display device, the width of a black matrix (6) is made larger above the region between adjacent ITO transparent electrodes (3) and is made smaller above the region between adjacent Al reflective electrodes (4). This enables a transmissive portion to offer a display with high contrast that does not suffer from afterimage or the like by shielding light from the domain lying between the adjacent pixels, and the reflective portion to offer a brighter display by increasing the aperture ratio thereof by making the black matrix width as small as possible or forming no black matrix.Type: GrantFiled: April 12, 2010Date of Patent: November 23, 2010Assignee: Sharp Kabushiki KaishaInventors: Keisuke Yoshida, Ichiro Shiraki, Shingo Jogan, Hirofumi Katsuse
