Abstract

Provided is a display apparatus that improves luminous efficiency and reduces a driving voltage. The display apparatus includes: a first electrode and a second electrode separated from each other; an electron accelerating layer interposed between the first and second electrodes and accelerating and emitting electrons when a voltage is applied between the first and second electrodes; and a light emitting layer interposed between the second electrode and the electron accelerating layer and producing visible rays by the electrons emitted from the electron accelerating layer.
