OPTICAL FILTER FOR DISPLAY APPRATUS

摘要

PURPOSE: An optical filter for a display device is provided to improve transmittance while reducing reflectivity about incident light and to improve productivity while reducing manufacturing costs by simplifying structure. CONSTITUTION: An optical filter(100) for a display device comprises a transparent substrate(110), an electromagnetic wave shielding layer(120), and a low refractive index layer(130). The electromagnetic wave shielding layer is formed on the transparent substrate. The electromagnetic wave shielding layer is formed by repetitively laminating a first high refractive metal oxide layer, a first conductive metal oxide layer, a metal layer, a second conductive metal oxide layer, and a second high refractive metal oxide layer more than once. The low refractive index layer is formed on the electromagnetic wave shielding layer. The low refractive index layer is comprised of low refractive material.
