Abstract
There is provided an optical laminate excellent which secures adhesiveness between the (meth)acrylic resin film (base material film) and a hard coat layer, and can prevent a reduction in scratch resistance. An optical laminate according to an embodiment of the present invention includes: a base material layer formed of a (meth)acrylic resin film; a hard coat layer formed by applying, to the (meth)acrylic resin film, a composition for forming a hard coat layer containing a curable compound and inorganic nanoparticles; and a penetration layer having a thickness of 1.2 μm or more, the penetration layer being formed between the base material layer and the hard coat layer by penetration of the composition for forming a hard coat layer into the (meth)acrylic resin film, wherein a content of the inorganic nanoparticles is 1.5 wt % to 50 wt % with respect to a total of the curable compound and the inorganic nanoparticles.
