Title:
SHIELDING POLYESTER FILM
Document Type and Number:
WIPO Patent Application WO/2017/142287
Kind Code:
A1
Abstract:
An embodiment relates to a polyester film having a high light-shielding effect by using light-absorbing particles and light-diffusing particles, wherein the polyester film has an excellent light-shielding effect since three or more layers of the polyester film are formed such that the light of a light source is firstly blocked by a first light-shielding layer, and the remaining light is scattered or reflected by a light-scattering layer and then absorbed by a second light-shielding layer, and thus the polyester film can be used in various display fields requiring high light-shielding properties.
