1. A polarizing plate comprising:
a polarizer;
an optical laminate formed on one side of the polarizer and containing a polymer substrate and an antiglare layer; and
a thermoplastic resin layer formed on the other side of the polarizer and containing a (meth)acrylate resin,
wherein the polymer substrate contains a polymer resin and rubber particles having a cross-sectional diameter of 10 to 500 nm dispersed in the polymer resin,
wherein the antiglare layer contains a binder resin and organic fine particles or inorganic fine particles dispersed in the binder resin,
wherein fine protrusions having a diameter of at least 100 μm formed by aggregating the organic fine particles or inorganic fine particles are present on an outer surface of the antiglare layer and a ratio of the number of the fine protrusions on the outer surface of the antiglare layer is 50/m2 or less, and
wherein the rubber particles having a cross-sectional diameter of 10 to 500 nm exist in the antiglare layer only within 75% of the thickness of the antiglare layer from an interface between the polymer substrate and the antiglare layer such that the rubber particles having a cross-sectional diameter of 10 to 500 nm are not exposed to an outer surface of the antiglare layer.
