Abstract
Provided is a protective film including a substrate including a first surface and a second surface opposing each other, and a film portion on the first surface, wherein the film portion includes an organic compound including an aliphatic polyisocyanate, and a first particle dispersed in the organic compound, wherein the first particle includes a first hollow particle having an outer radius of about 125 nm to about 250 nm, and a first coupling compound disposed on the surface of the first hollow particle, and having a secondary amine or imine group, wherein the first particle and the organic compound are bonded through a urea reaction between the secondary amine or imine group and an isocyanate group.
