Filter layer for a display, a method of preparing a filter layer for a display and a display including a filter layer

摘要

A filter layer for a display and a method of preparing the filter layer, and a display including the filter layer are provided. The filter layer for a display includes oxide particles and nano-sized metal particulates adhered to the surface of the oxide particles. A surface plasma resonance (SPR) phenomenon is triggered at the interface of the oxide/metal to selectively absorb light of at least one predetermined wavelength.
