Organic light-emitting diode display device with pixel array

A display device comprising:

• a plurality of power lines disposed to extend along a first axis and to be distant from one another along a second axis;
• a plurality of first driving transistors, each of which is disposed on a first side along the second axis of respective one of the plurality of power lines and provided with a power-supply potential from the respective power line;
• a plurality of second driving transistors, each of which is disposed on a second side along the second axis of respective one of the plurality of power lines and provided with a power-supply potential from the respective power line;
• and
• a plurality of light-emitting elements of a first color, a plurality of light-emitting elements of a second color, and a plurality of light-emitting elements of a third color,
• wherein the plurality of power lines include a plurality of power line units disposed along the second axis,
• wherein each of the plurality of power line units consists of a first power line, a second power line adjacent to the first power line, and a third power line adjacent to the second power line,
• wherein a first driving transistor of the first power line drives a first light-emitting element of the first color,
• wherein a second driving transistor of the first power line drives a first light-emitting element of the second color,
• wherein a first driving transistor of the second power line drives a first light-emitting element of the third color,
• wherein a second driving transistor of the second power line drives a second light-emitting element of the second color,
• wherein a first driving transistor of the third power line drives a second light-emitting element of the first color,
• wherein a second driving transistor of the third power line drives a second light-emitting element of the third color,
• wherein the first light-emitting element of the first color is adjacent to the first light-emitting element of the second color along the first axis,
• wherein the first light-emitting element of the third color is adjacent to the first light-emitting element of the first color and the first light-emitting of the second color along the second axis,
• wherein the second light-emitting element of the first color and the second light-emitting element of the second color are adjacent to each other along the first axis and adjacent to the first light emitting element of the third color along the second axis, and
• wherein the second light-emitting element of the third color is adjacent to the second light-emitting element of the first color and the second light-emitting element of the second color along the second axis.
