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.
Claims19
A light emitting device comprising:
- a first substrate provided with a plurality of luminescent material regions formed thereon;
- a second substrate;
- and
- spacers for holding said first and second substrates opposite to each other at a predetermined space therebetween;
- wherein said spacers are respectively formed on mask regions formed between said luminescent material regions and each of said spacers comprises a mask layer and a single spacer body formed thereon and further wherein the mask layers are formed between each of the plurality of said luminescent material regions and further wherein the spacers are formed between groups of three of said luminescent material regions.
A light emitting device comprising:
- electrodes on a substrate;
- a plurality of distinct luminescent material regions respectively provided on said electrodes;
- mask layers for masking non-emission portions without said luminescent materials formed between each of said plurality of distinct luminescent material regions;
- a second substrate;
- spacers for holding said first and second substrates opposite to each other said spacers comprised of single spacer bodies respectively formed on selected mask layers selected from a plurality of said mask layers;
- wherein each of said spacers comprises the selected mask layer and said single spacer body.
A display device comprising:
- mask regions formed on a fluorescent screen panel adjacent each of a plurality of distinct Red, Green and Blue emission regions wherein spacer bodies are formed on mask regions located at an outer edge of groups of distinct Red, Green and Blue emission regions.
