Abstract
A light-emitting device which comprises as one unit a semiconductor light-emitting element; a first liquid for condensing the light from the semiconductor light-emitting element; a second liquid that is separate from but contacts the first liquid; an airtight space in which at least first liquid and second liquid are disposed; and first and second electrodes to which voltage is applied so as to change the shape of the interface between first liquid and second liquid and adjust the condensed state of the light from semiconductor light-emitting element.
