Display unit, display module, electronic device, and method for manufacturing the display unit

A method for manufacturing a display unit, comprising the steps of:

• forming a plurality of transistors over a first substrate;
• forming, over the plurality of transistors, a plurality of first conductive layers each electrically connected to at least one of the plurality of transistors;
• forming a first insulating layer over the plurality of transistors;
• forming a first semiconductor film, a light-emitting body, a second semiconductor film, a conductive film, and a second insulating layer in this order over a second substrate;
• directly bonding the first insulating layer and the second insulating layer such that the first substrate and the second substrate are attached to each other;
• separating the second substrate from the first semiconductor film;
• processing the first semiconductor film, the light-emitting body, the second semiconductor film, and the conductive film, to form a plurality of first semiconductor layers, a plurality of light-emitting layers, and a plurality of second semiconductor layers, and a plurality of first electrodes, in a matrix;
• forming, in the second insulating layer, a plurality of openings that reach at least one of the plurality of first conductive layers;
• forming a plurality of second conductive layers positioned in at least one of the plurality of openings;
• and
• forming a plurality of second electrodes electrically connected to at least one of the plurality of second semiconductor layers and at least one of the plurality of second conductive layers to form a plurality of light-emitting diodes.
