1. A light receiving device, comprising:
a pixel array unit that includes:
a plurality of pixels in a two-dimensional matrix, wherein each pixel of the plurality of pixels includes:
a first tap configured to detect charge photoelectrically converted by a photoelectric conversion unit; and
a second tap configured to detect the charge photoelectrically converted by the photoelectric conversion unit;
four vertical signal lines configured to output a detection signal, wherein
the detection signal is associated with the charge detected by at least one of the first tap or the second tap; and
the four vertical signal lines are arranged for at least one pixel column in the pixel array unit; and
a plurality of wirings, wherein
each wiring of the plurality of wirings is connected to a ground potential (GND), and
each vertical signal line of the four vertical signal lines has a wiring, of the plurality of wirings, on both sides of the each vertical signal line of the four vertical signal lines.
