Display filter, display device including the same, and method of manufacturing the same

A plasma display device, comprising:

• a plasma display panel including front and rear panels facing each other;
• a chassis base on the rear panel of the plasma display panel;
• and
• a display filter on the front panel of the plasma display panel, the display filter including:
• a base layer having a plurality of structures, the plurality of structures being projected from a first surface of the base layer,
• an external light shielding layer on the plurality of structures, the external layer being on an upper surface and on a first side surface of the structures, and
• an electromagnetic wave shielding layer on the plurality of structures, the electromagnetic wave shielding layer being on the upper surface and on a second side surface of the structures, the first and second side surfaces of the structures being opposite each other, and a portion of the external light shielding layer being between the structures and a portion of the electromagnetic wave shielding layer.

A method of manufacturing a display filter, comprising:

• forming a base layer having a plurality of structures, the plurality of structures being projected from a first surface of the base layer;
• forming an external light shielding layer on the plurality of structures, the external layer being formed by coating black material on an upper surface and on a first side surface of the structures;
• and
• forming an electromagnetic wave shielding layer on the plurality of structures, the electromagnetic wave shielding layer being formed by coating a conductive material on the upper surface and on a second side surface of the structures, the first and second side surfaces of the structures being opposite each other, and a portion of the external light shielding layer being between the structures and a portion of the electromagnetic wave shielding layer.
