Abstract
A light-emitting device according to the present invention includes: first insulators () arranged so as to face each other; an emitter () arranged between the first insulators; a second insulator () functioning as a base for the first insulators and the emitter; an electrode () arranged to face, or contact with, the first insulators partially; another electrode () contacting with the second insulator and interposing the second insulator between the electrode and itself; and a light-transmitting substrate () that faces the second insulator with the first insulators interposed somewhere and with the emitter interposed elsewhere. If the first insulators are extended to reach the light-transmitting substrate on a cross section including the first and second insulators, the emitter and the light-transmitting substrate, the ratio of the cross-sectional area of the emitter to the combined cross-sectional area of the first and second insulators and the light-transmitting substrate is defined so as to fall within a predetermined range.
