1. A light detection device comprising:
a first substrate;
a second substrate laminated in a stacked arrangement with the first substrate;
a photodiode arranged in the first substrate and configured to convert incident light into a photocurrent;
a first transistor arranged in the first substrate and configured to output an output voltage, the first transistor including a gate, a first terminal and a second terminal, the second terminal being coupled to a reference potential; and
a quantizer coupled to the first transistor and arranged in the second substrate, wherein an anode of the photodiode is coupled to a potential lower than the reference potential.
