Kind Code:
A1
Abstract:
Provided is a light-detection device having high reliability. This light-detection device is provided with a plurality of pixels and partition walls. The plurality of pixels are arrayed each including a color filter, a first photoelectric conversion unit that detects light in a first wavelength region that has passed through the color filter and performs photoelectric conversion to generate an electric charge, and an oxide semiconductor capable of storing an electric charge. The partition walls are located in gaps between the color filters of the plurality of pixels, and have a lower refractive index than that of the color filters.
