Abstract
A printing plate, a scattering layer and a method for fabricating the same, and a display apparatus are provided. The printing plate is formed with a plurality of protrusion structures thereon, and the protrusion structures have a maximum width of 1 nm-1000 nm. The scattering layer is obtained by printing using the printing plate, and has groove structures corresponding to the protrusion structures on the printing plate thereon. The scattering structure is used on an organic light emitting display device, which can increase the light extraction efficiency and the external quantum efficiency and improve the display quality.
