Abstract: An optical filter and a plasma display device including the same are provided. The optical filter includes a support layer, and a plurality of stripe-shaped structures arranged at predetermined intervals on one surface of the support layer and formed using a material having a different refractive index than a refractive index of the support layer. In the optical filter, incident light is reflected at an interface between the support layer and the structure due to a difference of the respective refractive indices.

Since the structure is formed using a material having a high transmittance, luminance loss of light generated by the display is also minimized.
