  • Publication number: 20120229712
    Abstract: In the present liquid crystal display device, a conventional first auxiliary capacitance trunk line 430 is formed to be narrow, and a second auxiliary capacitance trunk line 440 is additionally provided and disposed at the closest position to the periphery of a substrate. Thus, a shift register can be distanced from the periphery of the substrate without increasing a frame area as a whole, so that the shift register is not overlaid with a seal material. Moreover, the extent of an area overlaid with a seal material within a wiring area for providing signals to the shift register can be reduced.

  • Publication number: 20120200544
    Abstract: In a shift register that operates based on four-phase clock signals, including two-phase clock signals that are provided to odd-order stages and two-phase clock signals that are provided to even-order stages, of which phases are shifted by 90 degrees from each other, a potential of a first clock appears as a potential of a scanning signal, when a potential of a first node is at a high level, in each stage. In this configuration, the potential of the first node included in each stage is set to a high level based on a pulse of a scanning signal outputted from a pre-stage, and is set to a low level based on a pulse of a scanning signal outputted from a third stage after a stage concerned.

  • Patent number: 8207924
    Abstract: A display device improves brightness while minimizing an increase in the number of source drivers. When a value obtained by dividing the length of a display screen in a row direction by the number of pixels in the row direction is a length corresponding to one pixel in the row direction, one period of color arrangement in the row direction is a length corresponding to two pixels. One such period of color arrangement includes two groups of subpixels that include first subpixels of the light's three primary colors of red (R), green (G) and blue (B), that are arranged in a row and that have the same subpixel configuration; and at least one additional subpixel. Scanning lines extending in the row direction and signal lines extending in the column direction are connected to the first subpixels and the at least one additional subpixel.
