Abstract
An image sensor includes a light-incidence regulating layer for compensating for a refractive index deflection between a micro lens array and the atmosphere between the micro lens array and an external lens is disposed at an upper portion of the micro lens array, so that light incident on the micro lens array has a vertical direction irrespective of which portion of the external lens the light is transmitted through. Therefore, the light is incident upon all photo diodes in a semiconductor substrate in a vertical direction, and an amount of light received by the photo diodes is uniform irrespective of the positions of the photo diodes. Photocharges generated and accumulated by the photo diodes are also uniform, and the presentation quality of the image is greatly improved.
