    • A thin-film EL element which does not permit the color of the emitted light to change irrespective of a change in the voltage, which remains chemically stable and which emits light of high brightness even on a low voltage. The element comprises two or more polycrystalline thin light emitting layers (4, 5, 6) and one or more thin insulating layers (3, 7). The interface between a thin film and a thin film constituting a light emitting layer is formed by epitaxial growth, and the electrical characteristics of the element are equivalent to those of a single circuit which includes two Zener diodes (12, 13) connected in series, a capacitor (14) connected in parallel with the serially connected Zener diodes, and a capacitor (15) connected to one end of the capacitor (14).

    • A thin film EL element capable of emitting light of different colors desired even at a low applied voltage owing to its high luminescent efficiency and freedom from crystal defects. The thin film EL element is of the dual dielectric structure having a transparent substrate (1), and a transparent conducting film (2), a first dielectric layer (3), a luminescent layer (4), and a second dielectric layer (5), which are formed on top of the other on the substrate, the transparent conducting film and the second dielectric layer being provided with respective electrodes (6a, 6b). It is characterized in that the luminescent layer has a superlattice structure represented by (luminscent host material)/(luminescent host material):(luminescent center impurity). The luminescent layer permits the doping of various luminscent center impurities while keeping its electrical neutrality without a need for the addition of charge compensating elements.

    • In the present invention, an EL element section (1) includes a plurality of arranged cells, each including a thin film EL element formed so as to emit white light, and a like number of predetermined-color filters (2) formed on the surface of the EL element section and corresponding to the cells such that each cell is caused to emit light in accordance with image information and the emitted light is output through the corresponding color filter to color display purposes. Thus, a very thin color display apparatus is provided in which contrast is good and the dependency of the luminance on the visual sensation is also good. The thin film EL element according to the present invention uses a luminous layer of zinc sulphide containing nitrogen, so that transitional luminescence occurs among a plurality of levels, and hence rays of light having various wavelengths are emitted to thereby provide white light containing three primary colors.
