A light-emitting device is a light-emitting device that is made by sequentially laminating an insulating layer made of a high dielectric material, a phosphor, a light-emitting layer made of a high dielectric material, and a transparent conductive film formed by vapor-depositing a conductive material such as indium oxide. , is widely used in various technical fields. However, such an element that has both the functions of a piezoelectric element and a light emitting element does not yet exist.

。To explain this in detail based on the example shown below, ① is a back electrode of a predetermined size made of metal foil such as aluminum foil, 2 is barium titanate powder and cyan ethyl chloride with good polarization characteristics. The insulating layer 3 is made by dispersing a cellulose resin and coating it on the back electrode 1 and forcing it to dry.
-Cu) powder mixed therein is applied onto the insulating layer 2 and forcedly dried to form a luminescent layer; 4 is formed by vapor-depositing a conductive material such as indium oxide;
The transparent electrode bonded to the soil, 5 is the back electrode 1. It is a transparent moisture-proof film in which a laminate consisting of an insulating layer 21, a light-emitting layer 3, and a transparent electrode 4 is airtightly packaged.
It has a thickness of 0μ, and the mixing ratio of titanium barium and cyanoethylcellulose resin in the insulating layer 2 and the mixing ratio of the phosphor powder and cyanoethylcellulose resin in the light emitting layer 3 are both l:1. Met. As for the method of drawing out the terminal plate from each electrode 1.4, the method used in conventional light emitting elements was used as is.

認した。The light-emitting piezoelectric element according to the present invention is constructed as described above, but according to experiments, 100% of the gap between the back electrode 1 and the transparent electrode 4
When a DC intermittent wave (4ooHz) voltage of V was applied,
We were able to obtain fluorescent light emission and vibrating sound that were sufficiently usable for practical use. In this case, it has been confirmed that when an AC voltage of, for example, 100 .mu.m is applied, only fluorescence is emitted without generating any vibration noise.
