To provide an optical laminate capable of having high transmissivity, achieving simultaneously high scratch resistance and anti fouling property, achieving low reflectance and having colorless transparent properties, a polarizer including the optical laminate, a display unit containing the optical laminate, and an organic light emission diode display unit including the optical laminate.SOLUTION: An optical laminate comprises: a polymer resin layer; and an optical functional layer which is formed on one surface of the polymer resin layer and includes a binder resin and hollow type organic nano particles and solid type organic nano particles dispersed in the binder resin. The optical laminate has a specific volume ratio of a zirconium element to a silicon element in a portion from an interface between the polymer resin layer and the optical functional layer to a thickness 5 nm to 10 nm region of the optical functional layer and a portion from the interface between the polymer resin layer and the optical functional layer to a thickness of 50 nm to 150 nm of the optical functional layer. There are also provided a polarizer comprising the same optical laminate, a display device, and an organic light emission diode display unit.SELECTED DRAWING: Figure 1 【課題】本発明は、高い透光率を有し、かつ高い耐スクラッチ性および防汚性を同時に実現することができ、低い反射率を実現しながらも、無色透明な特性を有する光学積層体、前記光学積層体を含む偏光板、前記光学積層体を含むディスプレイ装置、及び前記光学積層体を含む有機発光ダイオードディスプレイ装置を提供する。【解決手段】本発明は、高分子樹脂層、および前記高分子樹脂層の一面に形成され、バインダ樹脂と前記バインダ樹脂に分散した中空型無機ナノ粒子およびソリッド型無機ナノ粒子を含む光学機能層；を含み、前記高分子樹脂層と光学機能層の間の界面から前記光学機能層の厚さ５ｎｍ～１０ｎｍ領域と前記高分子樹脂層と光学機能層の間の界面から前記光学機能層の厚さ５０ｎｍ～１５０ｎｍの領域で、それぞれシリコン元素に対するジルコニウム元素の特定体積比を有する光学積層体と前記光学積層体を含む偏光板、ディスプレイ装置および有機発光ダイオードディスプレイ装置に関する。【選択図】図１
