ABSTRACT:
Disclosed are an external light-shielding layer for a display filter preventing occurrence of ghosting using a difference between refractive indexes of a base substrate and an external light-shielding part, and a display filter and display apparatus including the external light-shielding layer. The external light-shielding layer for the display filter comprises a base substrate made of a transparent resin; and at least one external light-shielding part arranged on a surface of the base substrate and filled with an external light-absorption material, wherein nyof a refractive index of the base substrate is less than or equal to nxof a refractive index of the external light-shielding part.
