ABSTRACT:
An external light-shielding layer capable of enhancing a visible light transmittance and a contrast ratio and preventing Moiré fringe and Newton ring phenomena, a display filter including the external light-shielding layer, and a display device including the display filter. The external light-shielding layer includes a transparent resin matrix, and a plurality of light-shielding patterns formed on the transparent resin matrix and spaced apart from each other in a predetermined interval, wherein a bias angle (α) formed between a traveling direction of the light-shielding patterns and the longer side of the matrix is in a range of about 5 to 80 degrees.
