Display panel and electronic device including same

A display panel comprising:

• a plurality of metal layers on each of a first sub-pixel, a second sub-pixel, and a third sub-pixel;
• a first insulating layer covering the plurality of metal layers;
• a first reflective layer on an upper portion of the first insulating layer of the first sub-pixel;
• a second insulating layer covering the first reflective layer;
• a second reflective layer on the second insulating layer of the second sub-pixel;
• a third insulating layer covering the second reflective layer;
• a third reflective layer on the third insulating layer of the third sub-pixel;
• a plurality of first electrodes on the third insulating layer of each of the first to third sub-pixels;
• and
• a plurality of holes penetrating the first to third insulating layers of each of the first to third sub-pixels,
• wherein the metal layer of each of the first to third sub-pixels is electrically connected to the first electrode of each of the first to third sub-pixels through each hole of the plurality of holes.
