Abstract
A gate driver is provided with an odd-numbered stage shift register, an even-numbered stage shift register, and main lines including clock signal main lines. In at least one example embodiment, each stage of one of the shift registers receives the first clock and the second clock from the clock signal main lines, and the third clock and the fourth clock from an adjacently provided stage of the other shift register. Each stage of the shift register can receive the second clock from a different stage of the same shift register. With this, it is possible to reduce a picture-frame area of a panel in a display device provided with a scanning signal line drive circuit having the plurality of shift registers.
Claims9
A scanning signal line drive circuit capable of driving a plurality of scanning signal lines provided on a display unit of a display device, the scanning signal line drive circuit comprising:
- a plurality of shift registers each including a plurality of stages, and configured to sequentially shift a pulse supplied to a first stage based on a plurality of clock signals supplied to each stage to drive the scanning signal lines;
- and
- clock signal main lines including a plurality of signal lines configured to respectively transmit the clock signals, and provided on an opposite side of the display unit with respect to the shift registers, wherein
- the plurality of shift registers is disposed on one side of the display unit,
- the plurality of shift registers includes an odd-numbered stage shift register constituted only by odd-numbered stages and an even-numbered stage shift register constituted only by even-numbered stages, and
- each stage of one of the shift registers is configured to receive a part of the clock signals from the clock signal main line, and a remaining part of the clock signals from both an adjacently provided preceding stage and an adjacently provided succeeding stage of another one of the shift registers.
