Light source device and display apparatus

摘要

Provided are a light source device which may disperse a force shifted in a plane direction due to a difference in thermal expansion by a reflection sheet so as to maintain good display quality, and a display apparatus using the light source device. The light source device includes a transparent plate used as a light guide plate, a light source disposed to face a part of a peripheral surface of the transparent plate along the part thereof, and a reflection sheet attached to one wide surface of the transparent plate, and the reflection sheet is provided with a plurality of cut lines formed in a prescribed range including a center thereof at a prescribed interval. Thereby, even if the transparent plate and the reflection sheet are thermally expanded in relation to the different expansion coefficients from each other, it is possible to prevent the reflection sheet from being peeled off from the transparent plate.
