Display device and mobile electronic device including the same

A mobile electronic device comprising:

• a display device including a display panel in which a light emitting element is disposed on a substrate,
• wherein the display panel includes:
• a driving element layer disposed on the substrate and including a plurality of pixel driving circuits for driving a plurality of pixels;
• and
• a light emitting element layer disposed on the driving element layer and including the light emitting element of each of the plurality of pixels,
• wherein transistors included in each of the plurality of pixel driving circuits are divided into a first transistor group connected to a first well region of the substrate and a second transistor group connected to a second well region of the substrate,
• the first well region and the second well region in each of the plurality of pixels are defined in a same surface portion of the substrate,
• the first well region and the second well region in each of the plurality of pixels are spaced apart from each other by a first interval when viewed in a thickness direction of the substrate,
• the plurality of pixels include a first pixel and a second pixel adjacent to each other in a first direction, and
• well regions adjacent to each other in the first pixel and the second pixel are spaced apart from each other by the first interval when viewed in the thickness direction of the substrate,
• wherein the first pixel is adjacent to the second pixel in the first direction, and
• wherein the first well region included in the first pixel is spaced apart from the first well region or the second well region of the second pixel by a second interval which is greater than the first interval.
