Abstract

A light source device includes a discharge lamp that has a first electrode and a second electrode opposed to each other in a hollow portion in which a discharge medium is enclosed and a driving device that supplies a driving voltage to the first electrode and the second electrode. The driving voltage is applied to the discharge medium through the first electrode and the second electrode such that the discharge medium emits light.
