Abstract
To provide an optically transparent film, a method of manufacturing the optically transparent film, an alignment film formed of the optically transparent film, and a liquid crystal panel and a display including the alignment film. The optically transparent film includes amorphous fluorocarbon. Preferably, the integrated transmittance of the optically transparent film is in the visible region is about 50% or higher when the optically transparent film has a film thickness of about 100 nm. The amorphous fluorocarbon has an atomic ratio between hydrogen atoms and fluorine atoms of about 1/9 or higher, and the transmittance in the visible region can be controlled by controlling the atomic ratio of fluorine atoms.
