THERMAL TRANSFER FILM, METHOD FOR PREPARING THE SAME AND ELECTROLUMINESCENCE DISPLAY DEVICE PREPARED USING THE SAME

摘要

The present invention relates to a thermal transfer film, a method for preparing the same and an electroluminescence display device prepared using the same. The thermal transfer film according to one embodiment of the present invention includes a substrate film; a photothermal conversion layer formed in the upper part of the substrate film; and a coating layer which is formed in the lower part of the substrate film. According to the embodiment of the present invention, the surface roughness of the photothermal conversion layer is 50 nm or less.
