Disclosed is an external light shielding film. The external light shielding film comprises a transparent substrate; and an external light shielding pattern formed on a surface of the transparent substrate and including a plurality of external light shielding parts. Each of the plurality of external light shielding parts has a polymer resin and at least one color-changeable colorant. The color of the plurality of external light shielding parts may vary according to an external heat source or vary depending on an intensity of an external light source, thereby improving a contrast ratio in a bright room, and a specific color may be visible even when the power of the display apparatus is OFF, thereby achieving an interior decorative effect.
