Abstract: A display apparatus having a light-emitting device and a touch electrode is provided. An optical pattern may be disposed on the light-emitting device. A side of the optical pattern may be sloped. A surface of the optical pattern opposite to the light-emitting device may be covered by an intermediate insulating layer. The intermediate insulating layer may be harder than the optical pattern. The touch electrode may overlap the side of the optical pattern. Thus, in the display apparatus, the surface defect of the optical pattern in the forming process of the touch electrode may be prevented. Therefore, in the display apparatus, the frontal luminance and the image quality may be improved.

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.

Abstract: A 3D display apparatus in which a display panel has a curvature is provided. A lower barrier layer, an upper barrier layer and lenticular lenses may be sequentially stacked on the display panel. The lower barrier layer and the upper barrier layer may include openings corresponding pixel areas of the display panel, respectively. Each opening of the lower barrier layer and each opening of the upper barrier layer may be disposed on an imaginary line passing through the corresponding pixel area of the display panel and a setting region. Thus, in the 3D display apparatus, the quality of the realized 3D image may be improved.
