摘要： PURPOSE:To improve uniformity of distribution of the dopant concentration in a mother material by forming electrode on both surfaces of a flat plate type fluorescent body in which dopant is dispersed for giving light emissiveness to Zn sulfide in the form of flat plate, and thereby accomplishing a light emitting element. CONSTITUTION:A clear electrode 5 consisting of ITO (In-Sn oxide) is formed in the upper part of a fluorescent body 8 in the form of flat plate consisting of ZnS incl. Cu and Cl as dopant, and a counter-electrode 6 consisting of Ag is formed in the lower part to provide a light emission part 9, whose two surfaces and sides are sealed by inorganic sealing 10 of low-melting point glass. ZnS in the form of flat plate is hard to transfer to hexagonal crystal even though it is heat treated at 1200 deg.C and remains in the cubic crystalline structure. Therefore, use of such ZnS to the mother material for fluorescent body admits a heat treatment of higher temp. than when powder ZnS is used. Thereby the dopant can be dispersed in the mother material at a high temp., and the dopant concentration in the mother material be distributed more uniformly.

摘要： PURPOSE:To improve the luminous efficiency by covering the back faces and both sides of multiple light source electroluminescence(EL) pixels having luminous layers with electrodes and connecting the electrodes of the EL pixels to the electrodes of a substrate. CONSTITUTION:EL pixels 20 are mounted on a ceramic substrate 25 while the first electrode 24 is closely stuck to a conductor 26, the back faces and both sides of the EL pixels 20 are covered by the second electrode 27 made of a metal thin film in this mounting state. This second electrode 27 serves as a common electrode and integrally and continuously covers the EL pixels 20 and concurrently covers the upper face of the ceramic substrate 25. This first electrode 24 is connected to the bottom face of the ceramic substrate 25 via a substrate electrode 28 in contact with the lower end of the conductor 26 and a power source 29, and the high electric field applied to the luminous layers 23 of the EL pixels 20 is obtained. The luminous efficiency is thereby improved.

摘要： PURPOSE:To dope a luminous center as a metal unit, to form a highly pure luminous center, and to improve the luminous brightness, by spattering a basic material and the luminous center as different targets respectively at a time. CONSTITUTION:On a transparent substrate 1, ITO or the like is attached to form a transparent electrode 2, over which an insulating layer 3 is formed. Then, a luminous layer 4 consists of a phosphor of a luminous center material made by adding an activating agent of a unit metal such as Ce, Eu, Mn, Tb, Sm, or Tm to a basic material such as ZnS, Cas, and SrS, and the luminous center material is selected and used adequately responding to the desired luminous color. And to form the luminous layer 4, the basic material and the luminous center material are loaded on target holders 7 and 8 separately, the ions of a spattering gas are struck at a time, and attached at a time on a substrate 11. which is loaded on a substrate holder 12 and rotated in a constant speed. In this case, by converting the size of the aperture in a regulating plate 14 adequately, the doping amount of the luminous center material to the basic material is controlled. After that, an insulating layer 5 and an opposite electrode 6 are formed.

摘要： PURPOSE:To hinder drop of the withstand voltage and prevent dielectric breakdown and burning phenomenon by coating one or more element layers with a coating liquid in which silicon compound expressed by a certain formula is dissolved, followed by baking, and by forming a coating layer. CONSTITUTION:On a transparent base board 1 made of glass etc., such layers are placed one over another, as a transparent electrode 2, insulating layer 3, EL light emitting layer 4, another insulating layer 5, and facing electrode 6. Thus a film type EL indication element is formed. Here one or more of these layers are coated with a coating liquid in which silicon compound is dissolved, that shall be expressed by the general equation RnSi(OH)4-n, where R represents alkyl radical, n a natural number of 4 or less. This is followed by baking to form a coating layer 10. These coating layers 10 enhance the withstand voltage of the indication element and prevent occurrence of dielectric breakdown.

摘要： PURPOSE:To prevent a seizure phenomenon even when an asymmetric wave driving is executed by doping an insulating layer with phosphorus. CONSTITUTION:In a membranous EL display element which is composed by laminating a transparent electrode 2, an EL (Electroluminescence) luminous layer 4, insulating layers 3 and 5 holding the luminous layer 4, and an opposite electrode 6 on a transparent substrate 1, the insulating layers 3 and 5 are doped with phosphorus. As a result, since sodium ions mixed in the insulating layers and/or at the interfaces between the insulating layers and the luminous layer can be trapped, a seizure phenomenon is suppressed even when an asymmetric wave driving is executed consequently, and a good display stabilization can be obtained.
