Display device

A display device comprising:

• a substrate;
• a first pixel electrode and a second pixel electrode spaced apart from each other, and above the substrate;
• a first type light-emitting element having a contact electrode above the first pixel electrode, and electrically connected to the first pixel electrode;
• a bonding electrode between the first pixel electrode and the contact electrode;
• a second type light-emitting element on the second pixel electrode;
• a filling layer between the first type light-emitting element and the second type light-emitting element;
• a connect electrode connecting the first type light-emitting element and the second type light-emitting element in series;
• and
• a common electrode above the first type light-emitting element and the second type light-emitting element, and electrically connected to the second type light-emitting element,
• wherein a height of the second pixel electrode is substantially equal to a sum of a height of the first pixel electrode, a height of the bonding electrode, and a height of the contact electrode.

An electronic device comprising a display device comprising:

• a substrate;
• a pixel electrode above the substrate;
• a first type light-emitting element above the pixel electrode, and having a contact electrode electrically connected to the pixel electrode;
• a second type light-emitting element above the pixel electrode, and having a non-contact electrode;
• a filling layer between the first type light-emitting element and the second type light-emitting element;
• a connect electrode connecting the first type light-emitting element and the second type light-emitting element in series;
• and
• a common electrode above the first type light-emitting element and the second type light-emitting element, and electrically connected to the second type light-emitting element.
