Display device

A display device comprising:

• a display region;
• and
• a frame region disposed around the display region,
• the frame region partly including a terminal section,
• the display region including
• display elements configured to perform display,
• pixel circuits configured to drive the display elements, and
• a plurality of power-source voltage lines configured to apply a power source voltage having a first potential to the display elements,
• each of the display elements including
• a first electrode, and
• a function layer,
• the display region being shared among the function layers,
• the display device comprising
• a second electrode configured to apply, to the display elements, a power source voltage having a second potential different from the first potential,
• wherein the frame region includes
• a main-power-source-voltage stem wire and an auxiliary-power-source-voltage stem wire both provided for applying, to the display elements, the power source voltage having the first potential or the power source voltage having the second potential,
• the frame region includes
• a first frame region having the terminal section, and
• a second frame region located opposite the first frame region with reference to the display region,
• the main-power-source-voltage stem wire has a potential different from a potential of the auxiliary-power-source-voltage stem wire, and
• the main-power-source-voltage stem wire disposed in the second frame region of the frame region and the auxiliary-power-source-voltage stem wire disposed in the second frame region of the frame region are electrically connected together via a switching transistor disposed in the second frame region.
