1. A color filter array, comprising:
a partition wall defining a plurality of sections that are partitioned from each other by the partition wall, the plurality of sections including a first section, a second section, and a third section; and
a first color filter in the first section and configured to selectively transmit light in a first wavelength spectrum, a second color filter in the second section and configured to selectively transmit light in a second wavelength spectrum, and a third color filter in the third section and configured to selectively transmit light in a third wavelength spectrum, the first wavelength spectrum, the second wavelength spectrum, and the third wavelength spectrum being different from each other and belonging to a visible light wavelength spectrum,
wherein each separate color filter of the first color filter, the second color filter, and the third color filter includes
a colored layer in a separate, respective section of the first section, the second section, and the third section, the colored layer including a colorant defining a respective wavelength spectrum of the first wavelength spectrum, the second wavelength spectrum, and the third wavelength spectrum, and
a transparent resin layer on the colored layer in the separate, respective section,
wherein the colored layer excludes any crosslinked product of any crosslinkable monomer, and
wherein the color filter array further includes a planarization layer, the planarization layer isolating transparent resin layers of separate, respective sections of the plurality of sections from each other.
