1. A display apparatus comprising:
a device substrate including a first pixel area;
a bank insulating layer on the device substrate, the bank insulating layer defining a first emission region in the first pixel area;
a light-emitting device including a lower electrode, a light-emitting layer, and an upper electrode, which are sequentially stacked on the first emission region of the device substrate;
a light-blocking pattern on the bank insulating layer, the light-blocking pattern including a first opening disposed on the light-emitting device; and
a first pixel lens on the first opening of the light-blocking pattern, the first pixel lens having a horizontal width that is larger than the first emission region,
wherein a location of the light-blocking pattern and a horizontal width of the first opening satisfy the below equation, where g1 is a vertical distance between the light-emitting layer and the light-blocking pattern, g2 is a vertical distance between a lower surface of the light-blocking pattern and the first pixel lens, PW is a horizontal width of the first pixel area, AW is a horizontal width of the first opening, and BW is a half of a horizontal width of the bank insulating layer in the first pixel area.
