1. A color filter array comprising:
a plurality of color filters arranged two-dimensionally, the plurality of color filters comprising a first color filter configured to transmit the light of the first wavelength range and a second color filter configured to transmit the light of the second wavelength range;
wherein each of the first color filter and the second color filter comprises at least one particle configured to scatter light incident thereon and a transparent dielectric surrounding the at least one particle,
wherein the color filter array further comprises an isolation wall arranged between the first color filter and the second color filter and configured to prevent interactions between particles of the first color filter and particles of the second color filter.
