Abstract:
1. A light-emitting device comprising: pixels arranged over a substrate in matrix form, each of said pixels comprising; a first light-emitting element over a substrate; a semiconductor element of an active first driving matrix electrically connected to a first electrode of the first light-emitting element; a second light-emitting element over the first light-emitting element, wherein a row electrode or a column electrode of the second light-emitting element is electrically connected to a second driving matrix different from the active first driving matrix; and an insulating film formed over the semiconduductor element and the first light-emitting element, and between the first light-emitting element and the second light-emitting element, wherein the insulating film is configured to electrically isolate the semiconductor of the active first driving matrix from the row or column electrode of the second light-emitting element such that the first and second light emitting elements can be independently controlled, wherein one of the row electrode and the column electrode is in contact with the insulating film formed over the semiconductior element and the light-emitting element, and the other of the row electrode and the column electrode is in contact with a sealing agent, wherein the first light-emitting element emits first light in a first direction, wherein the second light-emitting element emits light in a second direction that is opposite to the first direction, wherein the first light travels to outside of the light emitting device through the substrate in the first direction, and wherein the second light travels to outside of the light emitting device in the second direction.
