Abstract
The present invention aims to provide a low refractive index layer that can attain both a low refractive index and a high mechanical strength even when it has a large thickness. The low refractive index layer of the present invention is a low refractive index layer in the form of a void-containing layer, wherein hollow particles each having a void space inside are further contained in the void-containing layer, and the low refractive index layer has a refractive index of 1.25 or less.
