Publication number: 20100259715Abstract: An active matrix substrate (30) of the present invention includes a substrate, a gate line (50) formed on the substrate, and an interlayer insulating layer (90) for insulating a layer formed on the gate line (50) from the gate line (50). In a region of the substrate, the interlayer insulating layer (90) is not provided on an upper surface of the gate line (50), and therefore, the upper surface is exposed. On the other hand, the insulating layer (90) is provided on the substrate so as to have contact with at least an edge face of the gate line (50) which edge face is on an extension of a longitudinal direction of the gate line (50).Type: ApplicationFiled: August 4, 2008Publication date: October 14, 2010Inventors: Tetsunori Tanaka, Atsushi Ban, Tohru Senoo, Wataru Nakamura, Yukimine Shimada

Publication number: 20100253668Abstract: First and second data signal lines are provided for a column of pixels, and signal potentials of opposite polarity to each other are supplied to the data signal lines respectively. In at least one embodiment, a predetermined pixel is taken as the first pixel. A pixel other than the (2×n×i+1)-th pixel in the scanning direction is connected to a data signal line different from that connected to the previous pixel, whereas the (2×n×i+1)-th pixel is connected to the same data signal line as that connected to the previous pixel. The polarity of the signal potential supplied to each data signal line is inverted every n horizontal scanning periods. Every adjacent two scan signal lines starting from the scan signal line connected to the predetermined pixel are sequentially selected at the same time among scan signal lines. A liquid crystal display with this structure enables an increase of the pixel charging time as well as prevention of flickering.Type: ApplicationFiled: November 11, 2008Publication date: October 7, 2010Inventors: Toshinori Sugihara, Atsushi Ban, Toshihide Tsubata

Publication number: 20100214490Abstract: An active matrix substrate includes a transistor, a pixel electrode, a drain lead electrode connected with the drain electrode of the transistor, and a contact hole connecting the drain lead electrode and the pixel electrode. A non-electrode through-bore portion is created on the drain lead electrode, and an opening of the contact hole crosses the through-bore portion. As a result, any changes or decreases in the contact area between the drain lead electrode and the pixel electrode may be prevented or reduced significantly, while the open area ratio can be improved.Type: ApplicationFiled: July 28, 2006Publication date: August 26, 2010Applicant: SHARP KABUSHIKI KAISHAInventors: Toshihide Tsubata, Yoshihiro Okada, Atsushi Ban, Toshinori Sugihara
