ABSTRACT:
A display device comprising a light-absorbing layer comprising metal nanoparticles in a matrix material. Suitable matrix materials include organic materials, inorganic materials, polymeric materials, and combinations thereof. The metal nanoparticles may have various regular or irregular shapes and/or two-dimensional or three-dimensional structures. The metal nanoparticles may have a particle size of from about 2 to about 20 nm. In embodiments, the particle size distribution of the nanoparticles does not exceed +/−75%. The light-absorbing layer may have a multiple layer configuration comprising 2 or more individual light-absorbing layers. The light-absorbing layer(s) reduces the reflection of ambient light in a display device.
