Abstract

Disclosed is a display apparatus comprising a panel assembly including a plurality of light-emitting cells divided into a light-emitting region and a non light-emitting region surrounding the light-emitting region, as viewed from a viewer, and a display filter disposed on the panel assembly and including an external light-shielding layer, the external light-shielding layer having light-shielding patterns formed on a side of the external light-shielding layer, wherein an area of the light-emitting region occupies about 60% or more of a total area of the plurality of light-emitting cells, and wherein a bias angle formed by an advancing direction of the light-shielding pattern and a longitudinal side of the panel assembly is about 5 degrees or less. The external light-shielding layer is applied to the display apparatus, thereby effectively preventing the moiré phenomenon from being occurred.
