Abstract
An electrochromic composition, an anti-peep film, and a display device are provided. The electrochromic composition includes an acid-sensitive dye, an electrogenic acid, an ionic liquid, and a solvent. The acid-sensitive dye is capable of switching between a transparent state and a colored state in accordance with a change of proton concentration in the electrochromic composition. The electrogenic acid is capable of producing protons under action of external electrons. The ionic liquid is composed of dissociated ions. When the proton concentration of the electrochromic composition is 0, the acid-sensitive dye is in the transparent state. When the proton concentration of the electrochromic composition is greater than 0, the acid-sensitive dye is in the colored state.
