Abstract
The invention relates to a transfer sheet suitable for the formation of electrode patterns, dielectric layers, barrier layers, etc. in plasma display panels (PDPs), field emission displays (FEDS), liquid crystal displays (LCDs), fluorescent displays, hybrid integrated circuits, etc. The transfer sheet comprises a base film and a transfer layer releasably provided on the base film, optionally with a protective film provided on the transfer layer. The transfer layer comprises an inorganic component including a glass frit and an organic component removable by firing, optionally with an electrically conductive powder. By specifying the surface roughness and surface gloss of the transfer layer, the releasability of the transfer layer with respect to the base or protective film, and the residual solvent content of the transfer layer, it is possible to form, with high accuracy, primer layers, dielectric layers on front or back panel plates, photosensitive black matrix layers, and photosensitive rib layers for use with PDPS, and form high-definition electrode patterns as well.
