1. A light-emitting display apparatus comprising:
a substrate;
a first pixel electrode and a second pixel electrode over the substrate, the first and second pixel electrodes being apart from each other;
a pixel-defining layer comprising a first opening and a second opening that expose portions of the first and second pixel electrodes, respectively;
an intermediate layer comprising at least an emission layer and arranged over the first and second pixel electrodes;
a counter electrode covering the intermediate layer;
a continuous first inorganic layer covering the first opening, the second opening and the counter electrode
a first organic layer on the first inorganic layer, the first organic layer comprising first quantum dots and overlapping the first opening; and
a second organic layer on the first inorganic layer, the second organic layer comprising second quantum dots and overlapping the second opening,
wherein
the first organic layer and the second organic layer are apart from each other,
a total thickness of the first inorganic layer and the first organic layer in an area overlapping the first opening is greater than a total thickness of the first inorganic layer and the first organic layer over the pixel-defining layer, and
a total thickness of the first inorganic layer and the second organic layer in an area overlapping the second opening is greater than a total thickness of the first inorganic layer and the second organic layer over the pixel-defining layer.
