Display device

A display device, comprising:

• a substrate comprising:
• an emission part;
• and
• a transmission part;
• a planarization film at the substrate, the planarization film having an inclined portion between the emission part and the transmission part;
• an anode on the planarization film, the anode being disposed at the emission part;
• a bank to cover an edge of the anode and the inclined portion of the planarization film;
• an organic layer on the anode at the emission part, and on the transmission part;
• a common layer on the organic layer, the common layer comprising:
• an alloy comprising a first metal having an electron-injecting property;
• and
• a second metal different from the first metal;
• a cathode on the common layer at the emission part, the cathode comprising a single metal;
• and
• a capping layer on the cathode,
• wherein the capping layer is in contact with the common layer at the transmission part,
• wherein the common layer and the capping layer are provided at the transmission part, and the cathode is absent at the transmission part, and
• wherein the organic layer comprises a plurality of organic stacks each having a light emitting layer and at least one charge generation layer between adjacent organic stacks.
