Oled display device

An OLED display device, comprising:

• a first substrate including a plurality of control signal lines and a plurality of data signal lines crossing each other, and a plurality of pixels located in a matrix at intersections of the plurality of control signal lines and the plurality of data signal lines;
• and
• a second substrate facing the first substrate;
• wherein:
• the plurality of pixels each include:
• a pixel circuit to which a data voltage supplied from the corresponding data signal line is written in accordance with a control signal supplied from the corresponding control signal line;
• and
• an OLED display element including a first electrode supplied with a current from the pixel circuit in accordance with the data voltage, and a second electrode supplied with a power supply voltage;
• and
• the first substrate and the second substrate each include a plurality of power supply lines;
• the plurality of power supply lines of the first substrate and the plurality of power supply lines of the second substrate are respectively connected to each other via a conductive member;
• and
• each of the plurality of power supply lines is connected to the second electrode of the OLED display element.
