ABSTRACT:
It is an object of the present invention to provide a method that can provide regions having different thicknesses of a laminated body containing an organic compound with a light-emitting property in the same element and also can apply an electric field uniformly in all the regions of the element without depending on the thickness of the laminated body containing an organic compound with a light-emitting property. One laser element of the present invention has a laminated body containing an organic compound with a light-emitting property between two electrodes, and the laminated body includes a mixed layer of a metal oxide and an organic compound, which has a thickness distribution. The laser element emits light having different wavelengths in regions having different thicknesses of the mixed layer of a metal oxide and an organic compound, by applying voltage between two electrodes to feeding a current.
