Introducing of As2Se3 as a contrasting intermediate layer into SnO2-As2Se3-ZnS(Mn, Cu)-Al structure allows one to increase 1.5 times the light contrast range of the device that facilitates the perception of symbol-alphabetic information. The bleaching of As2Se3 film under the action of moisture allows to control the state of the structure air-tightness. The absorption edge of As-Se film and the electrooptical characteristics of SnO2-ZnS(Mn, Cu)-Al active structure are investigated.
