Abstract
Provided are a filling film and a method of manufacturing an organic light-emitting display apparatus by using the filling film. The filling film includes a filling material, a first releasing film attached to a surface of the filling film, a second releasing film attached to another surface of the filling film, and a supporting layer attached to the second releasing film. The bonding force between the second releasing film and the supporting layer is greater than the bonding force between the filling material and the second releasing film.
