Display device

A display device having a substrate, the substrate comprising:

• a display unit in which a plurality of pixel circuits, and a common electrode for applying a common reference voltage to the plurality of pixel circuits are formed;
• N (integer satisfying N≧3) gate signal lines that extend in the display unit;
• a pair of gate driver circuits arranged on opposite sides of the display unit, each including N shift register circuits that are connected to the respective gate signal lines to supply a gate signal, said shift register circuits being arranged side by side;
• a pair of common voltage main lines that are arranged on opposite sides of the display unit from one another and arranged further outside of the gate driver circuits with respect to the display unit so that the display unit and the gate driver circuits are located between the pair of common voltage main lines;
• and
• M common voltage sub-lines that extend in M (1≦M<N−1) spacings among (N−1) spacings between the respective N shift register circuits which are arranged side by side, from the common voltage main lines to the common electrode.
