Abstract: A donor film for a flat panel display and a method of fabricating an Organic Light Emitting Device using the same. The donor film for the flat panel display has a base film, a Light-To-Heat Conversion layer disposed on the base film, a transfer layer disposed on the Light-To-Heat Conversion layer, and a buffer layer interposed between the Light-To-Heat Conversion layer and the transfer layer, wherein the buffer layer includes a material whose glass transition temperature (Tg) is lower than 25° C. The donor film for the flat panel display interposes the buffer layer between the Light-To-Heat Conversion layer of the donor substrate and the transfer layer, thereby improving the adhesion between the transfer layer and the donor substrate. Therefore, the organic layer pattern formed on an acceptor substrate by transferring the transfer layer using the donor film does not include any defect.

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.

Abstract: The present invention relates to a full color organic electroluminescent device and a method for fabricating the same and provides a full color organic electroluminescent device. The invention reduces misalignment errors caused by fine patterning of the emitting layer by reducing the steps of the fine patterning process. In particular, the blue emitting layer functions as a hole inhibition layer which results in superior color purity and improved stability for the color organic electroluminescent device. The use of such a blue emitting layer also reduces the manufacturing steps. The device comprises a substrate; a first electrode pattern formed on the substrate; a red emitting layer formed by patterning a red emitting material on a red pixel region of the first electrode pattern and a green emitting layer formed by patterning a green emitting material on a green pixel region of the first electrode pattern. A blue emitting layer is applied over the entire substrate, over the upper parts of the red and green emitting layers and a second electrode is formed on an upper part of the blue emitting layer.
