Title: Electroluminescent element
Inventor: KABASHIMA SHIROU
IPC: H05B33/12
Filed: 1988-01-26
Abstract: PURPOSE:To obtain a luminous element with a high brightness same as a membranous electroluminescence(EL), a stable voltage-resisting property, and an easy manufacturing, by specifying the capacity ratio of an insulating layer and a luminous layer in an MIS structure type of electric field luminous element. CONSTITUTION:A transparent electrode 2 is formed on a transparent type front side substrate 1, over which a luminous layer 3 is formed in a vacuum evaporation or a spattering, and a heat treatment is applied. Then, an insulating layer 4 is formed by printing a slurry which is made by dispersing a powder of a high dielectric constant in a binder of an organic compound on the layer 3. In this case, the ratio of the capacity Ci of the layer 4 to the capacity Cl of the layer 3, Ci/Cl, is made 0.3-0.5. The larger the ratio Ci/Cl, the larger the brightness, but when it exceeds 0.5, a dielectric breakdown is liable to be generated, making an unstable condition. Consequently, the brightness at the level same as a membranous EL at a low cost and in a stable structure is obtained by making the ratio Ci/Cl in said scope.
