摘要： A buffer film and an organic light emitting device (OLED) including the same are disclosed herein. In some embodiments, a buffer film comprises a porous metal sheet having average reflectance of 50% or less for light in a wavelength range of 400 to 800 nm. The buffer film can exhibit heat dissipation properties, electromagnetic wave shielding properties and impact resistance (or impact mitigation properties) required for an OLED. The buffer film is capable of securing the characteristics required for an OLED without price increase, process complexity, and thickness increase of the OLED.
