ABSTRACT:
A method of manufacturing a fluorescent layer having a striped or dot pattern for a display device, including the steps of installing a donor film composed of a base film, a light absorbing layer, a buffering layer and a phosphor layer being departed from a substrate by predetermined distance, and irradiating an energy source to the donor film to transfer a phosphor from the phosphor layer to the surface of the substrate and then thermally treating the transferred phosphor. In the method, defects generated by dust or foreign substances are reduced so that manufacturing yield is improved compared to the conventional method. Also, the process is simple so that productivity is enhanced and a high resolution screen is realized.
