The present invention relates to a low refractive layer and an anti-reflective film comprising the same. The low refractive layer can exhibit excellent optical properties such as a low reflectance and a high light transmittance, and excellent mechanical properties such as high wear resistance and scratch resistance at the same time, without adversely affecting the color of the polymer resin forming the low refractive layer. In particular, due to the excellent alkali resistance, the low refractive layer can maintain excellent physical properties even after alkali treatment. Therefore, when introducing a low refractive layer to the display device, it is expected that the production process can be simplified and further the production rate and the productivity can significantly increase.

The optical multilayer film, which comprises a laminate in which a base layer, a primer layer, a hard coat layer, a first refractive layer, and a second refractive layer are sequentially laminated, has a very low reflectance and enhanced optical characteristics 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 a low reflectance and excellent other optical characteristics.
