PURPOSE: A display filter is provided to prevent corrosion due to external exposure of a reflection barrier layer by coating titan-zinc oxide on the outer-most refractive layer of the reflection barrier layer. CONSTITUTION: A display filter(10) comprises a transparent substrate(13), a reflection barrier layer(12), and a pollution preventing layer(11). The reflection barrier layer is coated on the transparent substrate by as a high refraction layer and a low refraction layer with a sputtering method. The pollution preventing layer in which titan-zinc oxide is coated with the sputtering method is coated on the outer-most refractive layer of the reflection barrier layer. The thickness of the pollution preventing layer is more than 5nm and less than 28nm. |
