Abstract:
1. A solid-state imaging device comprising a plurality of unit pixels which are two-dimensionally arranged, wherein each of said unit pixels includes: a photoelectric conversion part which converts incident light into electric charges; a vertical lens layer which is formed above said photoelectric conversion part, and which is generated by forming a film through which the incident light is transmitted; and a lens layer that includes a plurality of light-transmission films each including concentric circles, that is formed on and around said vertical lens layer, and that collects the incident light and outputs the incident light to said vertical lens layer through said light-transmission films, wherein in which in each of said plurality of light-transmission films, a ratio of a total line-width to a periodic width varies based on a plurality of zones, each of which is obtained by dividing said light-transmission film by a predetermined periodic width in an in-plane direction.
