Abstract:
1. A display comprising: a substrate having a display region; at least one light-emitting device on the substrate within the display region; a protective film covering the display region and each light-emitting device in the display region, the protective film comprising a plurality of silicon nitride layers, wherein, the protective film comprises an uppermost silicon nitride layer, a lowermost silicon nitride layer and a silicon nitride layer between the uppermost and lowermost silicon nitride layers, the protective film covers an upper light emitting surface and sidewalls of each light emitting device so as to seal in each light-emitting device individually, the lowermost silicon nitride layer is adjacent each light emitting device and is adjacent the upper light emitting surface and the sidewalls of each light emitting device, each of the uppermost silicon nitride layer and the lowermost silicon nitride layer has a higher density than that of a the silicon nitride layer between the uppermost silicon nitride layer and the lowermost layer, the density of each of the uppermost silicon nitride layer and the lowermost silicon nitride layer is 6.2×10 the uppermost silicon nitride layer has a density greater than that of the lowermost silicon nitride layer.
