Abstract: A display apparatus including a display panel and an eyepiece is provided. The eyepiece may include a right-eye lens corresponding to a right eye of a user and a left-eye lens corresponding to a left eye of the user. The display panel may provide a right-eye image through the right-eye lens and a left-eye image through the left-eye lens. The display panel may include an encapsulation structure covering light-emitting devices, a black matrix on the encapsulation structure, and optical lenses on the black matrix. The black matrix may extend in a first direction and a second direction perpendicular to the first direction between the light-emitting devices. Each of the optical lenses may extend in the second direction. Each of the optical lenses may overlap at least two light-emitting devices adjacent in the first direction and a portion of the black matrix disposed between the corresponding light-emitting devices. Thus, in the display apparatus, an overlap between a right-eye image and a left-eye image provided to the user by a single-display panel may be minimized or reduced.

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.
