Abstract:
1. A method of producing an electroluminescent device, the method comprising: positioning a laser thermal transfer sheet on a device substrate comprising a substrate and an electroluminescent layer disposed on the substrate, a passivation layer, and a transparent image-receiving layer disposed on the passivation layer, the laser thermal transfer sheet comprising a photothermal conversion layer that converts laser light to heat and a thermal transfer layer containing a colorant disposed in this order on a support that is transmissive with respect to light of a laser wavelength, such that the thermal transfer layer contacts the transparent image-receiving layer; irradiating a predetermined region of the laser thermal transfer sheet from the support side with laser light; and forming a color filter layer by removing the laser thermal transfer sheet from the transparent image-receiving layer to transfer the region of the laser thermal transfer sheet that has been irradiated with laser light to the transparent image-receiving layer, wherein the transparent image-receiving layer is formed by contacting, to the passivation layer, a sheet comprising a support, a cushion layer and an image-receiving layer, and removing the support and the cushion layer at an interface between the image-receiving layer and the cushion layer, thereby transferring the image-receiving layer onto the passivation layer.
