摘要： An electroluminescent display panel formed of phosphor and dielectric layers sandwiched between opposing mutually intersecting arrays of drive electrodes, has the thickness of the phosphor layer set to a value which provides minimum power consumption, for a given level of display brightness. This is achieved by determining a value of capacitance per unit area of the panel which results in a maximum allowable value of time being required to charge each display element, then determining a value of phosphor layer thickness providing minimum power consumption, using the latter value of capacitance and the known value of light emission efficiency of the display.

摘要： In a thin film electroluminescent element comprising a phosphor thin film, a dielectric thin film disposed on at least one of the surfaces of the phosphor thin film and electrodes for applying a voltage across the thin films, the aforementioned dielectric thin film is formed of a dielectric material expressed by a general formula of AB.sub.2 O.sub.6 (where A represents a divalent metal element and B represents a pentavalent metal element). By employing the dielectric material, the voltage for driving a thin film electroluminescent element can be lowered without decreasing the brightness of the element. Further, by using a composite dielectric thin film in which the dielectric thin film expressed by the aforementioned general formula AB.sub.2 O.sub.6 is laminated with a dielectric thin film which is not susceptible to dielectric breakdown of self-healing type, the composite dielectric thin film is made susceptible to the dielectric breakdown of self-healing type. Additionally, the value of product of the dielectric breakdown field intensity and dielectric constant is increased to obtain a thin film electroluminescent element having excellent characteristics.

摘要： The development of a dielectric thin-film which is high (140 MV/cm or above) in product of dielectric constant .epsilon..sub.i and dielectric breakdown field strength E.sub.ib is essential for realizing an EL element which can operate stably at a low voltage. Such dielectric film is also required which can withstand heat treatments at high temperatures above 500.degree. C. and is proof against clouding and in which the electrical breakdown caused by a minute fault produced in the process of film formation is self-healed. A film material which satisfies all of these requirements could be obtained from a TiO.sub.2 -BaO based composition by partially substituting the position of Ti with Sn, Zr or Hf and also partially substituting the position of Ba with Ca or Mg. By using these dielectric films, it is possible to obtain a low-voltage drive thin-film electroluminescent element which are high in production yield and reliability.
