Display device and method for manufacturing the same

A display device comprising:

• a substrate;
• a thin film transistor on the substrate;
• a first electrode connected to the thin film transistor;
• a light emitting layer on the first electrode;
• and
• a second electrode on the light emitting layer and comprising a metal material and a graphene material,
• wherein a Raman spectrum result of the second electrode has an Id/IG value of 0.03 or less and an I2D/IG value of 1 or more.

A method for manufacturing a display device, the method comprising:

• forming a thin film transistor on a substrate;
• forming a first electrode connected to the thin film transistor;
• forming a light emitting layer on the first electrode;
• and
• forming a second electrode on the light emitting layer, the second electrode comprising a metal material and a graphene material,
• wherein the graphene material is deposited by using a plasma enhanced chemical vapor deposition method using plasma.
