Background technology
In recent years, the growing demand of large scale, high integrated, high precision and high reliability display has been promoted the development of a lot of graph processing techniques.These technology have been applied to the manufacturing of plasma display panel (PDP).
According to typical PDP base plate production technology, on the whole surface of substrate, form electrode, dielectric layer and barrier layer continuously, thereby implement to peel off formation barrier (barrier ribs) through etching then.Before etching, on barrier, apply photosensitive photoresist (PR) or laminating film resist (DFR), use the salpeter solution of 0.4-6wt% to implement to peel off then as remover.Yet peeling off to increase the risk of peeling off that makes electrode end be exposed to stripper, but or the terminal shape of evoked electrode in a period of time, change.Therefore, between electrode end, may be short-circuited, thereby cause the formation of defective (the for example vertical stripes after the panel-mounted).PR solution applies or guard electrode and the stripper isolation and cause interrupted defective fully of DFR lamination.
One of approach that addresses these problems is at the composition that improves the glass dust that in electrode, uses aspect the acid resistance.In being used to form electrod composition, the main glass dust that uses based on lead oxide (PbO), for example PbO-SiO 2-P 2O 5And PbO-B 2O 3Yet in the world wide, restriction becomes urgent day by day based on the adjustment policy of the use of the glass dust of PbO, because exist poisonous and cause the lead of environmental pollution to the mankind in this glass dust.Under these circumstances, exist replacing demand based on the material of the glass dust of PbO.From the angle of this demand, compare with glass dust based on PbO, at present preference is used no Pb glass dust and based on the glass dust of Bi.Yet, during the barrier etching, because its relatively poor acid resistance is more responsive to infringement than the glass dust based on PbO based on the glass dust of Bi.In the trial that overcomes this infringement sensitiveness, think SiO 2Interpolation improved acid resistance based on the glass dust of Bi.Yet, the SiO of increase 2Content causes glass transition temperature (Tg) and the dilatometer softening point of glass dust to improve inevitably, thereby necessarily requires higher firing temperature, and after the firing of multiaspect plate, causes the PDP base plate deformation.Therefore, there is demand in the improved glass dust that is used for photoactive electrode, said glass dust can guarantee good acid resistance, keeps the fundamental characteristics of electrode simultaneously, and even under up to 560-590 ℃ temperature, also can not cause base plate deformation.
