One embodiment of the present invention provides an optical film 10 which is provided with a glass substrate 11 that has a thickness of from 30 μm to 200 μm (inclusive) and a resin layer 12 that is adjacent to the glass substrate 11. With respect to this optical film 10, the Young's modulus of the resin layer 12 at 25°C is from 70 MPa to 1,200 MPa (inclusive). Un mode de réalisation de la présente invention concerne un film optique 10 qui comprend un substrat de verre 11 qui a une épaisseur comprise entre 30 µm et 200 µm (inclus) et une couche de résine 12 qui est adjacente au substrat de verre 11. Par rapport à ce film optique 10, le module d'Young de la couche de résine 12 à 25 °C est compris entre 70 MPa et 1200 MPa (inclus). 本発明の一の態様によれば、厚さが３０μｍ以上２００μｍ以下のガラス基材１１と、ガラス基材１１に隣接した樹脂層１２と、を備え、樹脂層１２における２５℃でのヤング率が、７０ＭＰａ以上１２００ＭＰａ以下である、光学フィルム１０が提供される。
