1. A display apparatus comprising:
a first light-emitting element on a substrate and configured to implement a first emission area by emitting light in a first wavelength band;
a second light-emitting element on the substrate and configured to implement a second emission area by emitting light in a second wavelength band that is different from the first wavelength band;
a low reflection layer on the first light-emitting element and the second light-emitting element and including an inorganic material;
a touch sensing layer on the low reflection layer and including a first touch electrode layer, a second touch electrode layer, a first touch insulating layer between the first touch electrode layer and the second touch electrode layer, and a second touch insulating layer on the second touch electroe, wherein the first touch insulating layer covers the first emission area and includes a first opening overlapping the second emission area, and the second touch insulating layer covers the first emission area and includes a second opening overlapping the first opening;
a light-blocking layer on the touch sensing layer and including a third opening corresponding to the first emission area and a fourth opening corresponding to the second emission area; and
a reflection-adjusting layer on the light-blocking layer wherein a refractive index of the reflection-adjusting layer is higher than a refractive index of the second touch insulating layer.
