This article proposes an advanced theoretical framework that quantitatively evaluates dispersion state of silica beads of a PET‐based antiglare film. The positional randomness of bead dispersion is expressed via a single scalar value, the dynamic dispersity index. The static dispersity index definition based on molecular dynamics, which was proposed in our previous work, was improved with a pseudo‐relaxation algorithm. PET‐based antiglare films, which had the variable degree of particle dispersion, were used for the verification together with graphically drawn artificial bead images. © 2013 Wiley Periodicals, Inc.
