Display device

A display device, comprising:

• a plurality of pixel circuit substrates, wherein the pixel circuit substrates overlap each other;
• a plurality of light emitting devices electrically connected to at least one of the pixel circuit substrates;
• a driver circuit substrate located on a back side of the pixel circuit substrates in a manner of being parallel to the pixel circuit substrates;
• a plurality of connection terminals electrically connecting the driver circuit substrate to the pixel circuit substrates;
• and at least one electrically conductive adhesion layer located between the pixel circuit substrates and the driver circuit substrate, wherein each of the pixel circuit substrates comprises:
• a first substrate, wherein the plurality of connection terminals penetrate the first substrate;
• and a plurality of pixel circuits located on the first substrate and electrically connected to the plurality of connection terminals.
