Donor substrate for laser transfer and organic electroluminescence display device manufactured using the same
Abstract:
A donor substrate for laser transfer comprises: a base film; a light-to-heat conversion layer formed on the base film; and a transfer layer formed of an organic material on the light-to-heat conversion layer. The transfer layer contains a thermosetting electroluminescent material, and an organic electroluminescence display device is manufactured using the same. Thus, R, G and B emission layers are simply formed with a fine pattern by a thermal curing process after laser transfer. As a result, the emission layers are not damaged, and the manufacturing cost of a full-color organic electroluminescence display device is reduced due to employment of a simplified mask process. The donor substrate is advantageous to use in the manufacture of a large-sized organic electroluminescence display device.
