Display device, display module, electronic device, and method for fabricating display device

A display device comprising a substrate, a plurality of transistors, and a plurality of light-emitting diodes,

• wherein the plurality of light-emitting diodes are provided in a matrix over the substrate,
• wherein each of the plurality of light-emitting diodes includes a first semiconductor layer in direct contact with the substrate, a light-emitting layer over the first semiconductor layer, and a second semiconductor layer over the light-emitting layer,
• wherein each of the plurality of transistors is electrically connected to at least one of the plurality of light-emitting diodes,
• wherein the plurality of light-emitting diodes are positioned closer to the substrate than the plurality of transistors are, and
• wherein the plurality of light-emitting diodes emit light to an opposite side of the substrate.
