The present invention provides a donor substrate used in forming a light emitting layer by forming a transfer layer containing light emission material, irradiating a radiation ray to the transfer layer while the transfer layer and a substrate to be transferred face each other, and sublimating or vaporizing the transfer layer so that the transfer layer is transferred to the substrate to be transferred. The donor substrate includes: a base; a photothermal conversion layer arranged on the base; and a heat interfering layer arranged between the base and the photothermal conversion layer, and including two or more layers with refraction index different from each other.
