Abstract
A light emitting device having transparent electrodes deposited in stripes on a glass substrate of a fluorescent screen panel, and black mask layers provided in stripes between respective electrodes so as not to overlap the transparent electrodes. Fluorescent materials are respectively formed on the transparent electrodes. Because the black mask layers do not overlap the transparent electrodes, the fluorescent materials have similar pattern to that of the transparent electrodes and do not overlap the black mask layers. Accordingly, the transparent electrodes and fluorescent materials may be finely patterned.
