Abstract

Light detection elements with improved detection sensitivity are disclosed. In one example, a light detection element includes a light reception section that generates a charge according to an amount of received light; a voltage conversion section that acquires the charge via an input node, converts the charge into a voltage signal, and outputs the voltage signal from an output node; a signal amplification section that amplifies the voltage signal; and a comparison section that compares the amplified voltage signal with a predetermined voltage. The voltage conversion section includes an amplification circuit connected between the input node and the output node; and a feedback circuit connected between the input node and the output node, and a gate insulating film of at least one transistor included in the feedback circuit is thicker than gate insulating films of transistors included in the signal amplification section and the comparison section.
