    摘要： The present invention provides a fluorescent substance excellent both in quantum efficiency and in temperature characteristics, and also provides a light-emitting device utilizing the fluorescent substance. This fluorescent substance contains an inorganic compound comprising a metal element M, a trivalent element M1 other than the metal element M, a tetravalent element M2 other than the metal element M, and either or both of O and N. In the inorganic compound, the metal element M is partly replaced with a luminescence center element R. The crystal structure of the fluorescent substance is basically the same as Sr3Al3Si13O2N21, but the chemical bond lengths of M1-N and M2-N are within the range of ±15% based on those of Al—N and Si—N calculated from the lattice constants and atomic coordinates of Sr3Al3Si13O2N21, respectively. The fluorescent substance emits luminescence having a peak in the range of 490 to 580 nm when excited with light of 250 to 500 nm.

    摘要： A display device has an array formed on a substrate including a cathode wiring line layer, a gate wiring line layer and an insulating layer for electrically insulating the cathode wiring line layer and the gate wiring line layer from each other. Holes are formed at the crossing portion between the cathode wiring line layer and the gate wiring line layer so as to penetrate through the insulating layer, and resistive layer and an emitter layer are provided in the holes. The resistive layer has such a structure that conductive fine particles are dispersed in a base material of insulating fine particles, and the emitter layer is formed of a fine particle material. The insulating layer between the cathode electrode lines and the gate electrodes is formed of a silicon oxide film containing fluorine. When a large number of elements are formed over a large area in an electron emission device using fine particle emitters, there can be provided electron emission elements which can suppress the unevenness of the electron emission amount. According to the present invention, there can be provided a large-area and uniform display device which can be operated with a low driving voltage, and have a long lifetime.
