摘要：
An optical functional film which exhibits excellent optical characteristics without using an alignment film, and having the excellent adhesion property between layers. The optical functional film includes: a substrate having a property as an optically negative C-plate, and an optical functional layer formed on the substrate and having a rodlike compound. The optical functional layer is formed directly on the substrate, and the rodlike compound forms a random homogeneous alignment in the optical functional layer.
