Title:
PHOTODETECTOR AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/270023
Kind Code:
A1
Abstract:
Provided is a photodetector capable of reducing output differences generated between adjacent pixels. This photodetector comprises a plurality of pixels arranged in a matrix. Each of the pixels is provided with: a pixel structure including a photoelectric conversion layer which photoelectrically converts incoming light beams and a wiring layer which is layered on a surface of the photoelectric conversion layer on the opposite side to the light-entering surface and at which signal charges generated in the photoelectric conversion layer are read out; and a polarization unit that is disposed on the light-entering surface side of the photoelectric conversion layer, that has a polarizer having, in a plan view, an angle different for each of the pixels, and that allows transmission of a light beam having a specific polarizing direction among light beams that have entered through the polarizer. The polarizers have angles not orthogonal or parallel to the pixel structure in the plan view.
