Zusammenfassung:	To provide a light source device enabling reduction in thickness and capable of performing local dimming with a small number of light sources.SOLUTION: A light source device comprises a plurality of light guide plates 21 grouped into one or more groups Q, and optical modules 23 provided correspondingly to each of the one or more groups Q. The optical module 23 comprises a first light source that emits light to enter a plurality of light guide plates 21 belonging to the corresponding group Q, and a first optical switch that switches a light incident destination of the light of the first light source so that light of the first light source is incident on at least one of the light guide plates 21 belonging to the corresponding group Q.SELECTED DRAWING: Figure 3 【課題】薄型化を図りつつ、より少ない光源でローカルディミングを行うことができる光源装置を提供する。【解決手段】光源装置は、１以上のグループＱにグループ化されている複数の導光板２１と、１以上のグループＱ夫々に対応して設けられた光モジュール２３とを備える。光モジュール２３は、対応するグループＱに属する複数の導光板２１に入光させる光を出射する第１光源と、対応するグループＱに属する導光板２１のいずれか１以上に、第１光源の光を入光させるように第１光源の光の入光先を切替える第１光スイッチとを備える。【選択図】図３
