Abstract
An object of the invention is to provide a light reflective film which can prevent moire fringes from occurring. A rough face in which a plurality of rows of pyramidal convex portions that are linearly continuous are adjacently formed in parallel with one another is formed on one face of a die film. The rows of convex portions that are linearly continuous are inclined at a predetermined angle with respect to an edge of the die film. An optical film is produced by transferring the die film. A light reflective film is produced by vapor-depositing a light reflection film on the optical film. In a liquid crystal display panel having the light reflective film, the pitch of occurring moire fringes becomes so small that the moire fringes cannot be visually seen, and moire fringes can be prevented from occurring.
