Title:
PHOTOCURABLE CONDUCTIVE PASTE AND PHOTOCURABLE BLACK PASTE USED FOR FORMING BUS ELECTRODE HAVING TWO-LAYER STRUCTURE, AND PLASMA DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2007/123270
Kind Code:
A1
Abstract:
A photocurable conductive paste (A), which is used for forming upper layers of bus
electrodes (4a, 4b) having a two-layer structure with different contrasts, contains
a glass powder (A1) having a softening point higher, by 40˚C or more, than
that of a glass powder (B1) of a photocurable black paste (B) used for forming lower
layers, a conductive powder (A2), an organic binder (A3), a photopolymerizable monomer
(A4) and a photopolymerization initiator (A5). The photocurable black paste
(B) used for forming lower layers of the bus electrodes (4a, 4b) contains the glass
powder (B1) having a softening point lower, by 40˚C or more, than that of
the glass powder (A1) of the photocurable conductive paste (A) used for the upper
layers, a heat-resistant black pigment (B2), an organic binder (B3), a photopolymerizable
monomer (B4) and a photopolymerization initiator (B5). Consequently, stable
interlayer conductivity can be obtained in the lower layer of the bus electrode
having a two-layer structure.
