前記位相差フィルムは、
フィルム面に対し突刺し冶具の先端を垂直に押圧し、破断が生じたときの、
前記突刺し冶具の先端から前記位相差フィルムへ加えられた応力Ｆ（ｇ）と前記位相差フィルムのひずみ量Ｓ（ｍｍ）を用いて下記式（１）にて算出される突刺し弾性率が１５ｇ／ｍｍ以上５０ｇ／ｍｍ以下であることを特徴とする、ここで、該ひずみ量Ｓは該フィルムの突刺し方向の撓みによる変位量であり、突刺し弾性率の測定は、該フィルムを中央部が３０ｍｍ×３０ｍｍの正方形で切り抜かれた糊付き台紙に貼合した測定試料を用い、先端径が１ｍｍφ０．５Ｒである突刺し冶具の先端を０．３３ｃｍ／秒の速度で押圧する条件において測定され、前記位相差フィルムは、重合性液晶化合物である棒状液晶化合物が硬化した、垂直配向性を有する転写型位相差層を含み、前記位相差フィルムは（メタ）アクリレート系モノマーの硬化物を含む転写型配向層をさらに含み、前記転写型配向層の鉛筆硬度は３Ｂ以下であり、かつ、前記転写型配向層の厚さは１００ｎｍ〜１００００ｎｍである、光学積層体。
（１）突刺し弾性率（ｇ／ｍｍ）＝Ｆ（ｇ）／Ｓ（ｍｍ）
An optical laminate having a retardation film
The retardation film is
When the tip of the piercing jig is pressed perpendicularly to the film surface and breakage occurs,
The puncture elastic modulus calculated by the following equation (1) using the stress F (g) applied to the retardation film from the tip of the puncture jig and the strain amount S (mm) of the retardation film. It is characterized in that it is 15 g / mm or more and 50 g / mm or less, where the strain amount S is the amount of displacement due to the deflection of the film in the puncture direction, and the measurement of the puncture elastic modulus is centered on the film. Measured under the condition that the tip of a piercing jig with a tip diameter of 1 mm φ0.5 R is pressed at a speed of 0.33 cm / sec, using a measurement sample attached to a glued mount cut out in a square of 30 mm × 30 mm. The retardation film contains a transfer-type retardation layer having a vertical orientation in which a rod-shaped liquid crystal compound which is a polymerizable liquid crystal compound is cured, and the retardation film contains a cured product of a (meth) acrylate-based monomer. An optical laminate further comprising a transfer-type alignment layer, the transfer-type alignment layer having a pencil hardness of 3B or less, and the transfer-type alignment layer having a thickness of 100 nm to 10,000 nm.
(1) Puncture elastic modulus (g / mm) = F (g) / S (mm)
前記前面板は、前記偏光板における前記位相差フィルムが積層された側とは反対側に配置される請求項４に記載の光学積層体。The optical laminate according to claim 4, wherein the front plate is arranged on the side of the polarizing plate opposite to the side on which the retardation film is laminated.
