Abstract
Provided are a light source device capable of suppressing the occurrence of wrinkles on an optical sheet even if the optical sheet expands due to heat generated at the time of light emission, and a display apparatus including the light source device. In the light source device, an optical sheet is disposed with one surface facing the light source unit, while the light source unit and the optical sheet are supported by a support member. A contact portion being in contact with the peripheral edge part of the other surface of the optical sheet is pressed to the optical sheet by a connecting member, and the optical sheet is held between the contact portion and the support member. The contact portion and the support member holding the optical sheet are connected with each other by the connecting member. The connecting member is configured to have a weakened force of pressing the contact portion if a surrounding temperature reaches a predetermined temperature or higher.
