Abstract
To suppress deterioration of image quality. A solid-state imaging device () according to an embodiment includes a first vertical signal line (VSLk) and a second vertical signal line (VSLk), a current mirror circuit () connected to the first and the second vertical signal lines, a first unit pixel () connected to the first vertical signal line, a second unit pixel (+1) connected to the second vertical signal line, a first unit cell (D) connected to the first vertical signal line, a second unit cell (D) connected to the second vertical signal line, a current supply line (VCOM) connected to the first and the second unit pixels and the first and the second unit cells, and a constant current circuit () connected to the current supply line. A first amplification transistor of the first unit pixel, a second amplification transistor of the second unit pixel, the current mirror circuit, and the constant current circuit constitute a first differential amplifier circuit, and a third amplification transistor of the first unit cell, a fourth amplification transistor of the second unit cell, the current mirror circuit, and the constant current circuit constitute a second differential amplifier circuit.
