Abstract: PROBLEM TO BE SOLVED: To provide an electroluminescent element with a ferroelectric electron emission source which secures stable high current even at a low operating voltage. SOLUTION: In this electroluminescent element, a first insulating layer 2 is provided on a semiconductor substrate 1, a first electrode 3 to which a specific pulse power is applied is provided on the first insulating layer 2, a ferroelectric layer 4 emitting electrons after the pulse power is applied thereto covers the first electrode 3, a second electrode 5 connected to a ground power is provided on the ferroelectric layer 4, an electroluminescent layer 6 which emits light excited by the electrons emitted from the ferroelectric layer 4 fills gaps in the second electrode 5, a second insulating layer 7 covers top of the second electrode 5 and the electroluminescent layer 6, and a third electrode 8 for accelerating the electrons injected into the electroluminescent layer 6 is provided on a top of the second insulating layer 7.
