1. An evaluation method for a device layer structure design of a light emitting device for evaluating outgoing light from the light emitting device including a structure having four or more layers of thin films, including a light-emitting layer, laminated therein, using an information processing apparatus, the method being characterized by including:

  • an input step of inputting parameters of the thin films constituting the light emitting device and information indicating a spectrum of light emitted from the light-emitting layer;

    a spectrum calculation step of generating information based on the parameters input in the input step and indicating the light emitting device divided into meshes only in the lamination direction of the thin films, and calculating a spectrum of outgoing light from the light emitting device by an FDTD method using the generated information and the information indicating the spectrum of the light emitted from the light-emitting layer input in the input step; and

    a spectrum information output step of outputting information indicating the spectrum of outgoing light from the light-emitting device calculated in the spectrum calculation step.
