Abstract
A display filter capable of enhancing the visible light transmittance and contrast ratio for a bright room condition and a display device including the same. The display filter includes a filter base, and an external light-shielding layer, disposed on a surface of the filter base, including a matrix made of a transparent resin and a plurality of wedge-shaped black stripes arranged parallel to each other at a surface of the matrix.
Claims22
A display filter comprising:
- a filter base;
- and
- an external light-shielding layer disposed on a surface of the filter base and having a matrix made of a substantially transparent resin and a plurality of wedge-shaped black stripes arranged parallel to each other at a surface of the matrix,
- wherein a pitch of the black stripes is smaller than a pitch of discharge cells of a panel assembly.

A display device comprising:
- a panel assembly including a substantially transparent front substrate and a rear substrate disposed to face each other, and a plurality of cells between the front substrate and the rear substrate;
- an external light-shielding layer disposed on a surface of the panel assembly and having a matrix made of a substantially transparent resin and a plurality of wedge-shaped black stripes arranged parallel to each other at a surface of the matrix;
- and
- a display filter facing the external light-shielding layer and having an antireflection shielding function and/or an electro magnetic radiation shielding function, a near-infrared ray wave shielding function, or a combination thereof,
- wherein a pitch of the black stripes is smaller than a pitch of discharge cells of a panel assembly.
