[종래 기술][Prior art]

플라즈마 디스플레이 패널은 플라즈마로부터 형성된 자외선 방사에 의하여 형광체를 여기시켜 화상을 구현하는 표시장치로서, 현재 반사형 교류구동 플라즈마 디스플레이 패널이 널리 사용되고 있다.BACKGROUND OF THE INVENTION A plasma display panel is a display device for realizing an image by exciting phosphors by ultraviolet radiation formed from plasma, and a reflective AC driving plasma display panel is widely used.

플라즈마 디스플레이 패널의 제조 방법을 도 1을 참조하여 설명한다.A method of manufacturing a plasma display panel will be described with reference to FIG. 1.

배면기판(1) 위에 다수의 어드레스 전극(2)을 형성하고, 이 어드레스 전극(2)과 배면기판(1) 전면에 유전층(3)을 형성하고, 상기 유전층(3) 위에 각각의 어드레스 전극(2)에 대응하여 라인 형태의 방전 공간을 구획하는 다수의 격벽(4)을 형성하고, 격벽(4) 사이에 형광층(5)을 형성한다.A plurality of address electrodes 2 are formed on the rear substrate 1, and a dielectric layer 3 is formed on the front side of the address electrode 2 and the rear substrate 1, and each of the address electrodes 3 is formed on the dielectric layer 3. Corresponding to 2), a plurality of partitions 4 are formed to partition the discharge space in the form of a line, and a fluorescent layer 5 is formed between the partitions 4.

그 다음 형광층(5)을 소성한 뒤 패널의 상, 하판을 조립, 봉착, 배기, 가스주입 및 에이징(aging)하여 플라즈마 디스플레이 패널이 제조된다.After the firing of the fluorescent layer 5, the upper and lower panels of the panel are assembled, sealed, exhausted, gas injected and aged to manufacture a plasma display panel.

격벽(4) 사이에 형광층(5)을 형성하는 방법은 형광체 페이스트 조성물을 격벽(4) 사이에 패턴 인쇄하고 소성하는 과정으로 이루어진다. 그러나 형광층 형성 과정에서 패턴 인쇄 후 인쇄마스크 배면에 형광체 페이스트가 잔류하게 되고 이 잔류한 형광체 페이스트는 다음 패턴 인쇄시의 이물질로 작용하여 플라즈마 디스플레이 패널의 혼색 불량을 야기하는 원인이 된다.The method of forming the fluorescent layer 5 between the partitions 4 consists of a process of pattern-printing and baking a phosphor paste composition between the partitions 4. However, in the process of forming the phosphor layer, the phosphor paste remains on the back of the printing mask after the pattern is printed, and the remaining phosphor paste acts as a foreign matter during the next pattern printing, causing a color mixing defect of the plasma display panel.

이러한 혼색 불량을 방지하기 위하여 인쇄 후 마스크배면 클리닝을 실시한다. 그러나 배면 클리닝이 깨끗하게 되지 않은 경우나 인쇄 공정 시간이 길어져클리닝을 빠르게 실시하지 않은 경우에 배면에 묻어 있는 형광체 페이스트가 건조되면서 유기용매가 증발하여 형광체 페이스트 조성물 중의 형광체 성분이 가루분으로 생성되고 이 가루분이 하판으로 이동하여 다른 색의 형광체 라인에 혼입되어 결국 혼색 셀결함을 발생하는 원인이 된다.In order to prevent such mixed color defects, mask back cleaning is performed after printing. However, when the back cleaning is not cleaned or the printing process is long and the cleaning is not performed quickly, the phosphor paste on the back is dried and the organic solvent evaporates to generate the phosphor component in the powder paste composition. It moves to the lower plate and is mixed in the phosphor lines of different colors, which eventually causes mixed color cell defects.

본 발명은 상술한 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 이물성 결함 및 형광체 혼색 결함이 억제되어 휘도가 높고 방전특성이 우수한 플라즈마 디스플레이 패널용 형광체 페이스트 조성물을 제공하는 것이다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a phosphor paste composition for a plasma display panel having high luminance and excellent discharge characteristics by suppressing foreign material defects and phosphor mixture defects.

본 발명의 다른 목적은 상기 형광체 페이스트 조성물을 소성하여 제조되는 플라즈마 디스플레이 패널을 제공하는 것이다.Another object of the present invention is to provide a plasma display panel manufactured by firing the phosphor paste composition.

상기 목적을 달성하기 위하여, 본 발명은 형광체; 유기바인더 수지; 유기용매; 및 가소제를 포함하는 플라즈마 디스플레이 패널용 형광체 페이스트 조성물을 제공한다.In order to achieve the above object, the present invention is a phosphor; Organic binder resin; Organic solvents; And it provides a phosphor paste composition for a plasma display panel comprising a plasticizer.

본 발명은 또한, 상기 형광체 페이스트 조성물을 소성하여 제조되는 플라즈마 디스플레이 패널을 제공한다.The present invention also provides a plasma display panel produced by firing the phosphor paste composition.

이하 본 발명을 더욱 상세하게 설명한다.Hereinafter, the present invention will be described in more detail.

본 발명의 플라즈마 디스플레이 패널용 형광체 페이스트 조성물은 필수 성분으로 형광체; 유기바인더 수지 및 유기용매 이외 가소제를 더욱 포함하는 것을 특징으로 한다.The phosphor paste composition for a plasma display panel of the present invention is a phosphor as an essential component; In addition to the organic binder resin and the organic solvent, it further comprises a plasticizer.

가소제는 고분자에 첨가되어 분자들 사이에서 고분자들이 3차원적인 그물구조로 가교되는 것을 방해함으로써 고분자의 가공성을 높여주는 역할을 하는 첨가제이다.The plasticizer is an additive that is added to the polymer and serves to enhance the processability of the polymer by preventing crosslinking of the polymer into a three-dimensional network between molecules.

이 가소제는 고분자의 2차 분자간력을 완화시켜 고분자의 연화점, 유리전이점, 열적 성질, 기계적 성질 등을 변화시키고, 비점이 높고 휘발성이 낮아 고분자의 운동성을 증가시키므로 분자들 사이에 분자간력을 완화시켜 고분자로 제조되는 각종 플라스틱 제품의 성형시 고분자의 유동성을 증가시켜 준다.This plasticizer relaxes the polymer's secondary intermolecular force to change the softening point, glass transition point, thermal properties, mechanical properties, etc. of the polymer, and increases the mobility of the polymer due to its high boiling point and low volatility. It increases the fluidity of the polymer when molding various plastic products made of polymer.

이들 가소제는 내휘발성을 비롯하여 내열성 등이 우수하므로 이 가소제를 포함하는 플라즈마 디스플레이 패널용 형광체 페이스트 조성물은 휘발성이 낮고 또한 형광체 파우더끼리의 응집력이 증가하여 형광체 가루분 생성이 억제된다.Since these plasticizers are excellent in heat resistance, heat resistance, etc., the fluorescent substance paste composition for plasma display panels containing this plasticizer is low in volatility, and the cohesion force of fluorescent substance powders increases, and generation | occurence | production of fluorescent substance powder is suppressed.

따라서 이와 같은 가소제를 포함하는 플라즈마 디스플레이 패널용 형광체 페이스트 조성물을 이용하여 형광층을 형성한 후 일반적인 방법으로 제조된 플라즈마 디스플레이 패널은 이물성 결함 및 형광체 혼색 결함이 억제되어 휘도가 높고 방전특성이 우수하다.Therefore, after forming a fluorescent layer using the phosphor paste composition for plasma display panel containing such a plasticizer, the plasma display panel manufactured by a general method has high luminance and excellent discharge characteristics because foreign matter defects and phosphor mixture defects are suppressed. .

본 발명의 플라즈마 디스플레이 패널용 형광체 페이스트 조성물에 포함되는 형광체로는 (Y,Gd)BO3:Eu(적색형광체), Zn2-xMnxSiO4:Y계열:Ba계열(단, x는 0.1내지 0.5이다.)(녹색형광체), BaMgAl10O17:Eu(청색형광체) 등이 바람직하게 사용될 수 있다.Phosphors included in the phosphor paste composition for plasma display panel of the present invention include (Y, Gd) BO 3 : Eu (red phosphor), Zn 2-x Mn x SiO 4 : Y series: Ba series (where x is 0.1). To 0.5) (green phosphor), BaMgAl 10 O 17 : Eu (blue phosphor) and the like can be preferably used.

또한, 본 발명의 플라즈마 디스플레이 패널용 형광체 페이스트 조성물에 포함되는 유기바인더 수지는 형광체 페이스트 조성물의 점도를 증가시키는 역할을 하며, 에틸 셀룰로오스, 니트로 셀룰로오스, 아크릴 수지 등의 바람직하게 사용될 수 있다.In addition, the organic binder resin included in the phosphor paste composition for plasma display panel of the present invention serves to increase the viscosity of the phosphor paste composition, it may be preferably used, such as ethyl cellulose, nitro cellulose, acrylic resin.

또한, 본 발명의 플라즈마 디스플레이 패널용 형광체 페이스트 조성물에 포함되는 유기용매는 형광체 파우더를 용해시키며 유기바인더 수지로 인하여 증가된 형광체 페이스트 조성물의 점도를 적절히 저하시켜 형광체 페이스트 조성물의 인쇄성을 향상시킨다.In addition, the organic solvent included in the phosphor paste composition for a plasma display panel of the present invention dissolves the phosphor powder and appropriately lowers the viscosity of the increased phosphor paste composition due to the organic binder resin to improve the printability of the phosphor paste composition.

상기 유기용매로는 부틸 카르비톨 아세테이트(BCA), 테르피네올(TP), 톨루엔, 텍사놀, 부틸 카르비톨(BC), 또는 이들의 혼합물이 바람직하게 사용될 수 있다.As the organic solvent, butyl carbitol acetate (BCA), terpineol (TP), toluene, texanol, butyl carbitol (BC), or a mixture thereof may be preferably used.

또한, 본 발명의 플라즈마 디스플레이 패널용 형광체 페이스트 조성물에는 소포제, 분산제 등이 더욱 첨가될 수 있다. 상기 소포제 또는 분산제로는 실리콘 폴리에스테르 수지 등이 바람직하게 사용될 수 있다.In addition, an antifoaming agent, a dispersing agent, or the like may be further added to the phosphor paste composition for a plasma display panel of the present invention. As the antifoaming agent or dispersing agent, silicone polyester resin or the like may be preferably used.

본 발명의 플라즈마 디스플레이 패널용 형광체 페이스트 조성물에 첨가되는 가소제로는 하기 화학식 1의 디옥틸 프탈레이트 2-에틸헥실 프탈레이트(dioctyl phthalate 2-ethylhexyl phthalate), 하기 화학식 2의 디이소노닐 프탈레이트(diisononyl phthalate), 하기 화학식 3의 디옥틸 아디페이트 2-에틸헥실 아디페이트(dioctyl adipate 2-ethylhexyl adipate), 하기 화학식 4의 디부틸 프탈레이트(dibutyl phthalate), 하기 화학식 5의 디이소데실 프탈레이트(diisodecyl phthalate), 또는 이들의 혼합물이 바람직하게 사용될 수있다.Plasticizers added to the phosphor paste composition for a plasma display panel of the present invention include dioctyl phthalate 2-ethylhexyl phthalate of Formula 1, diisononyl phthalate of Formula 2, Dioctyl adipate 2-ethylhexyl adipate of formula 3, dibutyl phthalate of formula 4, diisodecyl phthalate of formula 5, or these Mixtures of may be preferably used.

본 발명의 플라즈마 디스플레이 패널용 형광체 페이스트 조성물에 첨가되는 가소제의 함량은 플라즈마 디스플레이 패널용 형광체 페이스트 조성물에 대하여 0.5 내지 10 중량%가 바람직하고, 0.5 내지 5 중량%가 보다 바람직하다.The content of the plasticizer added to the phosphor paste composition for a plasma display panel of the present invention is preferably 0.5 to 10% by weight, more preferably 0.5 to 5% by weight relative to the phosphor paste composition for a plasma display panel.

상기 가소제의 함량이 플라즈마 디스플레이 패널용 형광체 페이스트 조성물에 대하여 0.5 중량% 미만이면 형광체 페이스트 조성물의 건조시간을 지연시켜주는 효과가 미미하고, 10 중량%를 초과하면 형광체 페이스트 조성물 건조시 가소제가 증발되지 않고 잔류하여 형광층 소성과정에서 급격히 증가하게 되어 형광층면이 고르게 형성되지 않아 오히려 셀결함을 유발할 수 있다.If the content of the plasticizer is less than 0.5 wt% with respect to the phosphor paste composition for plasma display panel, the effect of delaying the drying time of the phosphor paste composition is insignificant. If it exceeds 10 wt%, the plasticizer does not evaporate when the phosphor paste composition is dried. It remains and rapidly increases during the firing of the fluorescent layer, so that the surface of the fluorescent layer is not evenly formed, which may cause cell defects.

또한, 형광층이 충분히 소성되지 않을 경우 상기 형광체 페이스트 조성물 중 잔류하는 가소제가 오히려 플라즈마 디스플레이 패널 내 잔류하여 형광체 발광을 저하시킬 수 있다는 문제점이 있어 바람직하지 않다.In addition, when the phosphor layer is not sufficiently baked, there is a problem that the plasticizer remaining in the phosphor paste composition may remain in the plasma display panel, thereby lowering phosphor emission.

본 발명은 또한, 상기 플라즈마 디스플레이 패널용 형광체 페이스트 조성물을 소성하여 제조되는 플라즈마 디스플레이 패널을 제공한다.The present invention also provides a plasma display panel produced by firing the phosphor paste composition for a plasma display panel.

이상 상세히 살펴본 바와 같이, 본 발명의 플라즈마 디스플레이 패널용 형광체 페이스트 조성물을 이용하여 제조되는 플라즈마 디스플레이 패널은 이물성 결함 및 형광체 혼색 결함이 억제되어 휘도가 높고 방전특성이 우수하다.As described in detail above, the plasma display panel manufactured by using the phosphor paste composition for plasma display panel of the present invention has high luminance and excellent discharge characteristics because foreign matter defects and phosphor mixed color defects are suppressed.
