1. A display apparatus comprising:
a first substrate;
a pixel electrode disposed over the first substrate;
a pixel-defining layer which covers an edge of the pixel electrode, wherein a pixel opening is defined through the pixel-defining layer to expose a central portion of the pixel electrode;
an emission layer disposed over the pixel electrode, wherein the emission layer emits light having a wavelength in a first wavelength band;
an opposite electrode disposed over the emission layer;
a second substrate disposed over the first substrate with the opposite electrode therebetween;
a bank disposed on a lower surface of the second substrate, wherein a bank opening, which overlaps the pixel opening and has an area greater than an area of the pixel opening when viewed from a direction perpendicular to the first substrate, is defined through the bank;
a quantum dot layer or a light-transmitting layer disposed in the bank opening; and
a filter-defining layer disposed between the bank and the second substrate, wherein a filter opening, which overlaps the pixel opening and has an area greater than the area of the pixel opening when viewed from the direction perpendicular to the first substrate, is defined through the filter-defining layer,
wherein
a distance between an upper surface of a portion of the opposite electrode overlapping the pixel opening in the direction perpendicular to the first substrate and a lower surface of the quantum dot layer or the light-transmitting layer in the direction perpendicular to the first substrate is defined as a first distance,
a distance between an edge of the filter opening and an edge of the pixel opening when viewed from the direction perpendicular to the first substrate is defined as a second distance, and
a ratio of the second distance to the first distance is greater than or equal to 0.625 and less than or equal to 1.
