Disclosed is a display device provided with a monolithic gate driver wherein the size and power consumption are reduced without deteriorating the display quality. A drive signal trunk line (71) for transmitting drive signals, such as clock signals ,is formed from a source metal (701) on a region which opposes the display region in relation to a shift register region. A VSS trunk line (73) for transmitting low-level DC power supply potential is formed from the source metal (701) on a region between the shift register region and the display region. The drive signal trunk line (71) and a bistable circuit constituting a shift register (410) are connected by means of a drive signal branch line (72) formed from a gate metal (702). The bistable circuit and the VSS trunk line (73) are connected by means of a VSS branched line (74) formed from the source metal (701).
