1. A light detecting device comprising:
first and second substrates;
an array of imaging pixels in the first substrate, wherein each imaging pixel comprises a photodiode;
row drive circuitry in the second substrate, wherein the row drive circuitry is configured to provide row control signals to the array of imaging pixels; and
failure detection circuitry in the first substrate configured to receive the row control signals from the row drive circuitry via a first connection portion,
wherein first circuitry of the failure detection circuitry does not include a photodiode and includes a first transistor coupled between a voltage supply line and a column signal line.
