摘要： To improve power efficiency of a light-emitting element for white emission even when light in a wavelength range of low luminosity is utilized. As a light-emitting element for white emission, three light-emitting layers are stacked. In such a light-emitting element, the three light-emitting layers are included between a light-transmitting electrode and a light-reflecting electrode, and light emitted from each light-emitting layer is reflected on the light-reflecting electrode and is transmitted through the light-transmitting electrode. In addition, the light-emitting layer closer to the light-reflecting electrode has a shorter optical path length. Thus, the position of each light-emitting layer is limited depending on the distance from the light-reflective electrode, and the optical path length of each light-emitting layer is adjusted; therefore the light-emitting element with high power efficiency can be provided.

摘要： An object is to provide a white light-emitting element which emits broad white light which is close to natural light and covers a wide wavelength range; that is, a white light-emitting element which has a broad spectrum waveform. Further, there are various different kinds of white light; however, in particular, an object is to provide a white light-emitting element which emits white light which is close to the standard white color of the NTSC. Over a substrate 100, a second light-emitting element 110 and a first light-emitting element 120 are stacked in series. The first light-emitting element 120 exhibits a light emission spectrum having two peaks (two peaks in the blue to green wavelength range) and is disposed close to a film of light-reflecting material. The second light-emitting element 110 exhibits a light emission spectrum having a peak in the orange to red wavelength range, and is disposed in a position which is not close to the film of light-reflecting material.
