Problems solved by technology

So the problem that arises is that when the pattern is baked in this state, the glass powder components are melted away by the baking process, making the surface flat to a certain extent, but the surface remains uneven, making the thickness of the pattern uneven

Abstract

A photosensitive inorganic paste composition capable of improving pattern accuracy to such an extent to be sufficiently adapted to fine patterning required of plasma displays, a sheet-shaped unbaked body for production of a plasma display front plate using the same, and a method of producing a plasma display front plate. A Norish type I photopolymerization initiator and a hydrogen-withdrawing photopolymerization initiator are used in combination as a photopolymerization initiator in a photosensitive inorganic paste composition comprising at least a photopolymerization initiator, a photopolymerizable monomer and inorganic powders.

Description

technical field [0001] The present invention relates to a photosensitive inorganic paste composition having an excellent pattern shape by photolithography, and an unbaked sheet for manufacturing a front panel of a plasma display using the composition, and also relates to a method for manufacturing a front panel of a plasma display method. Background technique [0002] The plasma display, which uses the discharge phenomenon of electrons to make a large number of tiny units self-illuminate to form an image, has excellent performances such as large area, thin, light and flat display. These advantages are beyond the reach of traditional displays, and this plasma The rollout of the displays has already begun. [0003] Conventional plasma displays are mainly composed of straight-structured cells having ribs in the vertical direction of the display. In recent years, however, a grid-structured cell having ribs not only in the vertical direction but also in the horizontal direction...
