    Abstract: An image sensor that provides a uniform sensitivity for pixels having color filters of the same color to increase the image quality is provided. The image sensor includes a substrate, a first grid pattern disposed on the substrate and including a first side wall and a second side wall opposite to the first side wall, a first pixel including a first photoelectric conversion element and a first color filter, and a second pixel including a second photoelectric conversion element and a second color filter. The first color filter contacts the first side wall and the second color filter contacts the second side wall. The first color filter and the second color filter are color filters of same color, and a first thickness of the first color filter is greater than a second thickness of the second color filter.

    Abstract: An organic image sensor may be configured to obtain a color signal associated with a particular wavelength spectrum of light absorbed by the organic image sensor may omit a color filter. The organic image sensor may include an organic photoelectric conversion layer including a first material and a second material. The first material may absorb a first wavelength spectrum of light, and the second material may absorb a second wavelength spectrum of light. The organic photoelectric conversion layer may include stacked upper and lower layers, and the respective material compositions of the lower and upper layers may be first and second mixtures of the first and second materials. A ratio of the first material to the second material in the first mixture may be greater than 1/1, and a ratio of the first material to the second material in the second mixture may be less than 1/1.
