Abstract: A color separation element array includes color separation elements which are two-dimensionally arranged to separate an incident light according to a wavelength such that a light of a first wavelength is directed to a first direction and a light of a second wavelength that is different from the first wavelength is directed to a second direction that is different from the first direction. Each of the color separation elements includes a first element and a second element that are sequentially arranged along a traveling direction of the incident light, and the first element and the second element of the color separation elements are symmetrically shifted with respect to a center area of the color separation element array, to be aligned to fit to the traveling direction of the incident light that is obliquely incident.

Abstract: An image sensor including a color filter isolation layer and a method of manufacturing the image sensor. The image sensor includes a plurality of color filters that transmit light of a predetermined wavelength band to a light sensing layer. The image sensor also includes an isolation layer disposed between adjacent ones of the plurality of color filters. The isolation layer is formed of a material having a lower refractive index than a refractive index of the color filters, thus totally internally reflecting light incident on the isolation layer from one of the plurality of color filters.
