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.

Abstract: Disclosed are a method of manufacturing an electrochromic display panel and an electrochromic display panel. The manufacturing method includes; manufacturing an array substrate, wherein the array substrate includes a base substrate, a driving layer, and a pixel electrode layer that are stacked in sequence, wherein the pixel electrode layer includes a plurality of sub-pixel electrode groups electrically connected to the driving layer; sequentially using the plurality of sub-pixel electrode groups as working electrodes, and forming a plurality of electrochromic layers disposed in one-to-one correspondence with the plurality of sub-pixel electrode groups by electrochemical polymerization. Different electrochromic layers have different display colors. When any one of the plurality of sub-pixel electrode groups is used as the working electrode, the working electrode is applied with a preset positive voltage, and any one of the electrochromic layers is formed on the corresponding working electrode.
