Scanning-signal-line driving circuit and display device including same

Abstract

In order to supply a low-level potential VSS from a trunk line (21) for the low-level potential VSS to each stage of a shift register (11), a branch line (22) and an auxiliary line (23) are provided for every plurality of stages of the shift register (11), and the auxiliary lines (23) are connected to the respective branch lines (22) and the plurality of stages of the shift register (11). It is also possible to provide an auxiliary line (23) having substantially the same length as the trunk line (21) and to connect all of the branch lines (22) and all of the stages in the shift register (11) to this auxiliary line (23). A high-level potential VDD may also be supplied using the same method. Consequently, a scanning-signal-line driving circuit is provided in which the frame area and power consumption of a display panel can be reduced when formed on the display panel as an integral unit.
