Display device

摘要

A display device includes a monolithic gate driver with drive signal trunk wiring lines that transmit drive signals (such as clock signals) made of a source metal in a region on the opposite side of a display region with respect to a shift register region. A VSS trunk wiring line arranged to transmit a low-level direct-current power supply potential is made of a source metal in a region between the shift register region and the display region. Each of bistable circuits defining a shift register and a drive signal trunk wiring line are connected by a drive signal branch wiring line made of a gate metal. Each bistable circuit and the VSS trunk wiring line are connected by a VSS branch wiring line made of a source metal.

主权项

1. A display device comprising:
a substrate; a pixel circuit formed in a display region for displaying an image, the display region being a part of an entire region on the substrate; a plurality of scanning signal lines formed in the display region and forming a part of the pixel circuit; a shift register that is formed in a part of the entire region on the substrate other than the display region and that includes a plurality of bistable circuits having a first state and a second state and that sequentially drives the plurality of scanning signal lines by the plurality of bistable circuits sequentially placed in the first state based on a plurality of clock signals, the plurality of bistable circuits being connected in series with each other and provided so as to have a one-to-one correspondence with the plurality of scanning signal lines; drive signal trunk wiring lines formed in a region on an opposite side of the display region with respect to a shift register region, and transmitting shift register drive signals including the plurality of clock signals, the shift register region being a region where the shift register is formed, and the shift register drive signals being signals for controlling operation of the plurality of bistable circuits; drive signal branch wiring lines that connect the drive signal trunk wiring lines to each bistable circuit; a direct-current power supply potential trunk wiring line that transmits a direct-current power supply potential to be provided to the plurality of bistable circuits; and a direct-current power supply potential branch wiring line that connects the direct-current power supply potential trunk wiring line to each bistable circuit, wherein the direct-current power supply potential trunk wiring line is formed in a region between the shift register region and the display region.
