1. A display apparatus comprising:
a light-emitting diode including a first electrode, a second electrode, and an emission layer between the first electrode and the second electrode;
a bank layer overlapping the first electrode of the light-emitting diode in a plan view and defining a first opening which defines an emission area of the light-emitting diode;
a first insulating layer on the light-emitting diode and having a first refractive index, wherein the first insulating layer includes a first portion overlapping the first opening and a second portion which is apart from the first portion with a main trench therebetween;
a second insulating layer on the first insulating layer, having a second refractive index different from the first refractive index, and defining a second opening which overlaps the first opening in the plan view; and
a third insulating layer on the second insulating layer and having a third refractive index different from the second refractive index.
