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

A method for manufacturing a display device comprising a first display element, a second display element, a first transistor configured to control driving of the first display element, and a second transistor configured to control driving of the second display element, comprising the steps of:

• forming the first transistor and a first electrode electrically connected to a source or a drain of the first transistor over a first substrate;
• forming a separation layer over a formation substrate;
• forming a second electrode over the separation layer;
• forming a second insulating layer over the second electrode;
• forming the second transistor and the second display element over the second insulating layer;
• bonding the formation substrate and a second substrate to each other with an adhesive;
• separating the formation substrate and the second electrode from each other;
• and
• forming the first display element by bonding the first substrate and the second substrate to each other with an adhesive so that a liquid crystal layer is positioned between the first electrode and the second electrode that is exposed,
• wherein the second transistor is between the first display element and the second display element.
