Abstract:
A display apparatus having a narrow viewing angle is provided. The display apparatus may include 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; 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 larger than the first emission region, wherein a horizontal width of the first opening is proportional to a vertical distance between the light-emitting layer and the light-blocking pattern. Thus, the central luminance of the pixel area may be improved.
