    Abstract: A light-emitting device is provided with a light source and a controller. The light source includes multiple light-emitting elements and multiple driving elements that are provided in correspondence with the light-emitting elements and drive the light-emitting elements to light up by going to an ON state. The controller controls a switching between a successive lighting operation that causes the light-emitting elements to light up successively and a simultaneous lighting operation that causes the light-emitting elements to light up simultaneously in parallel. The light source includes a power supply line set to a reference potential or a power supply potential, a driving signal line that is connected to the power supply line and that supplies a driving signal to the driving elements, and a lighting signal line that supplies a lighting signal for causing the light-emitting elements to light up. In the successive lighting operation, the controller sets the power supply line to the power supply potential and sets each driving element to the ON state with the driving signal and the lighting signal to cause each light-emitting element corresponding to each driving element to light up successively. In the simultaneous lighting operation, the controller sets the power supply line to the reference potential and also sets the driving elements to the ON state with the driving signal and the lighting signal to cause the light-emitting elements to light up simultaneously in parallel.
