Light-emitting device

A light-emitting device comprising:

• a first substrate comprising a plurality of first optical structure bodies at a bottom side of the first substrate;
• a first electrode over the first substrate comprising:
• a first light-transmitting conductive film;
• and
• a first light-reflecting conductive film;
• a second electrode over the first electrode comprising:
• a second light-transmitting conductive film;
• and
• a second light-reflecting conductive film;
• a light-emitting layer sandwiched between the first electrode and the second electrode, the light-emitting layer comprising:
• a plurality of first light-emitting regions in contact with and sandwiched between the first light-transmitting conductive film and the second light-reflecting conductive film;
• and
• a plurality of second light-emitting regions in contact with and sandwiched between the first light-reflecting conductive film and the second light-transmitting conductive film;
• and
• a second substrate over the second electrode, the second substrate comprising a plurality of second optical structure bodies at a top side of the second substrate,
• wherein each of the plurality of first light-emitting regions overlaps with a corresponding one of the plurality of first optical structure bodies, and
• wherein each of the plurality of second light-emitting regions overlaps with a corresponding one of the plurality of second optical structure bodies.
