Abstract
An image sensor includes a first unit. The first unit includes a first photodiode having a first dimension, a second photodiode disposed adjacent the first photodiode and having a second dimension that is greater than the first dimension, a first color filter overlapping the first photodiode and the second photodiode, and a first internal reflector disposed in the first color filter and overlapping the first photodiode. The first internal reflector has an inclined light receiving surface inclined from a top surface of the first color filter toward the second photodiode, and a refraction index of the first internal reflector is smaller than a refraction index of the first color filter.
