Abstract: An organic light emitting device and a display apparatus are disclosed. The organic light emitting device includes an array substrate and a package substrate (2); on a side of the package substrate (2) facing the array substrate, there is provided a protrusion (7) formed of a first transparent material, a surface of the protrusion (7) is also covered with a transparent layer (8) formed of a second transparent material, and the refractive index of the second transparent material is larger than the refractive index of the first transparent material. With the organic light emitting device, a part of light that is emitted from an organic light-emitting layer (5) and irradiated to a surface of the protrusion (7) is totally reflected and changed in optical paths to decrease incident light totally reflected at a boundary between the package substrate (2) and the outside air, and light that has been changed in optical paths is irradiated out through the package substrate (2) more easily, thereby improving the output efficiency of light.
