1. A display apparatus comprising:
an organic light emitting display panel comprising a base layer, a transistor on the base layer, a light emitting diode electrically connected to the transistor, and a thin film encapsulation layer on the light emitting diode;
a touch sensing unit on the thin film encapsulation layer, the touch sensing unit comprising:
a conductive layer on the thin film encapsulation layer; and
a silicon nitride layer on the thin film encapsulation layer and having a density of about 2.05 g/cm3 to about 2.4 g/cm3;
an organic adhesion layer on the touch sensing unit; and
a window facing the organic light emitting display panel, with the touch sensing unit and the organic adhesion layer being between the window and the organic light emitting display panel,
wherein the thin film encapsulation layer comprises:
a plurality of inorganic thin films; and
at least one organic thin film between the plurality of inorganic thin films.
