Abstract: A method of manufacturing a display apparatus includes preparing a substrate including a display area and a pad area outside of the display area, forming a sacrificial layer in the pad area, forming an encapsulation layer over the display area and the pad area, forming cracks in at least a portion of the encapsulation layer by increasing a volume of the sacrificial layer or by gasifying or evaporating at least a portion of the sacrificial layer, and removing at least a portion of the encapsulation layer in the pad area. A display apparatus is manufactured according to the manufacturing method.

Abstract: A display apparatus including a first sub-pixel, a second sub-pixel, and a third sub-pixel respectively representing different colors is provided. The apparatus includes an upper substrate, a functional layer disposed over the upper substrate and including a first quantum-dot layer and a second quantum-dot layer, and a color filter layer between the upper substrate and the functional layer and including a first color filter, a second color filter, and a third color filter. The first color filter corresponds to the first sub-pixel, the second color filter corresponds to the second sub-pixel, and the third color filter corresponds to the third sub-pixel. The first sub-pixel is a green sub-pixel, and a full width at half maximum of a transmission spectrum of the first color filter is in a range of about 45 nm to about 49 nm.
