Abstract
Provided are an optical member having adhesion and elastic restoring force, and a light source device and a display device including the same, the optical member including: a base film; an optical pattern layer provided on the base film and having adhesion; and an upper film partially adhering onto the optical pattern layer, in which at least a partial region of the optical pattern layer has a characteristic in which the partial region is deformed when external force is applied and restored when the external force is removed, and it is easy to assemble a product to improve productivity, and the elastic restoring force is excellent to suppress damage due to the external force.
