Abstract
The optical multilayer film, which comprises a laminate in which a base layer, a primer layer, and a hard coat layer are sequentially laminated, has enhanced mechanical properties while preventing rainbow stains and a reduction in the visibility by adjusting the in-plane retardation of the base layer and the refractive indices of the respective layers. Thus, the optical component and the display device, which comprise the optical multilayer film, have excellent optical characteristics and can operate normally even in harsh environments.
