Light emitting device

Abstract

A light emitting device includes: a light source board that includes a light emitting element including an anode and a cathode; a circuit board including a plurality of anode via conductors that conduct from a surface of the circuit board corresponding to a first direction up to a surface of the circuit board corresponding to a second direction opposite to the first direction, are connected to the anode, and are arranged in rows to form anode rows, and a plurality of cathode via conductors that conduct from the surface corresponding to the first direction up to the surface corresponding to the second direction, are connected to the cathode, are provided in the same number as the number of the anode via conductors, and are arranged in rows to form cathode rows, the circuit board holding the light source board on the surface corresponding to the first direction; and a drive unit that is connected to any one of the anode or the cathode and drives the light source board by switching between an ON state and an OFF state of current for causing the light emitting element to emit light, in which the anode rows of the plurality of anode via conductors included in the circuit board and the cathode rows of the plurality of cathode via conductors included in the circuit board are disposed to face each other.
