1. A display device comprising:
a substrate;
a plurality of light emitting units including a first light emitting unit and a second light emitting unit provided on the substrate, each of the plurality of the light emitting units including a first electrode, an organic later and a second electrode; and
a partition wall located between the first electrode of the first light emitting unit and the first electrode of the second light emitting unit, wherein
the partition wall includes a first insulating layer and a second insulating layer disposed on the first insulating layer,
a refractive index of the first insulating layer is higher than a refractive index of the second insulating layer, and
the first insulating layer is SiN or SiON and the second insulating layer is SiO.
