Abstract: Provided are a light source device capable of uniformly illuminating, a display apparatus, and a method of manufacturing the light source device. Since a reflection sheet is adhered to a light guide plate through an adhesive layer, deflection thereof is suppressed. Since dot parts are filled in openings of an optical layer, it would be difficult for the dot parts to be distorted by an outer force. In addition, since the dot parts are formed by forming the optical layer and the adhesive layer in a large area in which an occurrence of distortion during forming is minimal, it would be difficult for the dot parts to be distorted during forming the same. Therefore, an occurrence of luminance unevenness caused by the deflection of the reflection sheet or the distortion of the dot parts may be suppressed. From the above result, it is possible to uniformly illuminate by the light source device.
