Display device

A display device comprising:

• a flexible substrate including an active area, a non-active area and a bending area;
• the active area including pixels to display images, each pixel including:
• a first switching transistor, a second switching transistor, and a driving transistor,
• wherein the first switching transistor, the second switching transistor, and the driving transistor are formed of amorphous silicon or poly-crystalline silicon,
• wherein the first switching transistor includes a gate electrode connected to a first gate line, a source electrode connected to a data line, and a drain electrode connected to the driving transistor,
• wherein the driving transistor includes a gate electrode connected to the drain electrode of the first switching transistor, a source electrode coupled to drive an organic light emitting diode (OLED), and a drain electrode coupled to receive a driving voltage from a driving voltage line, and
• wherein the second switching transistor includes a gate electrode connected to a second gate line, a source electrode connected to the OLED, and a drain electrode connected to a voltage line;
• and
• a planarization layer on the flexible substrate where the driving transistor is formed;
• a first electrode on the planarization layer in the active area and connected to the drain electrode of the driving transistor through a contact hole of the planarization layer;
• a pixel defining layer that is on the first electrode, with a portion of the first electrode being exposed by the pixel defining layer;
• a light-emitting layer on the pixel defining layer and the exposed portion of the first electrode;
• a second electrode on the light-emitting layer, wherein at least a portion of the first electrode, the light-emitting layer, and the second electrode forms the OLED;
• the non-active area including a driving circuitry, the driving circuitry includes:
• a data driving portion mounted in the non-active area positioned below the active area;
• a gate driving portion in the non-active area outside the active area, in a form of a gate in panel (GIP);
• and
• a light-emitting controller in the non-active area outside the active area, in the form of the GIP, and outputting a light emitting signal provided from the data driving portion;
• at least two different power lines, wherein at least two or more power lines of the at least two different power lines are arranged directly on a same layer in the bending area between the data driving portion and the active area, wherein the at least two different power lines include a first power line supplying a voltage at a first level and a second power line supplying a voltage at a second level different from the first level.
