1. A display apparatus comprising:
a substrate;
a display element on the substrate;
a low-reflection inorganic layer on the display element;
a light-shielding layer on the low-reflection inorganic layer, the light-shielding layer comprising an opening corresponding to an emission area of the display element;
a first insulating layer on the light-shielding layer and comprising an opening corresponding to the emission area of the display element; and
a second insulating layer filling the opening of the light-shielding layer and the opening of the first insulating layer,
wherein the first insulating layer comprises a material configured to absorb light in a wavelength band of about 380 nm to about 500 nm, and
a thickness of the first insulating layer is greater than a thickness of the light-shielding layer.
 
13. A display apparatus comprising:
a substrate;
a first display element, a second display element, and a third display element on the substrate and configured to emit light of different colors;
a low-reflection inorganic layer on all of the first display element, the second display element, and the third display element;
a light-shielding layer on the low-reflection inorganic layer, the light-shielding layer comprising openings respectively corresponding to emission areas of the first display element, the second display element, and the third display element;
a first insulating layer on the light-shielding layer and comprising openings respectively corresponding to the emission areas of the first, second, and third display elements; and
a second insulating layer filling the openings of the light-shielding layer and the openings of the first insulating layer,
wherein the first insulating layer comprises a material configured to absorb light in a wavelength band of about 380 nm to about 500 nm, and a difference between a refractive index of the first insulating layer and a refractive index of the second insulating layer is from about 0.1 to about 0.2.
