본 발명은 플라즈마 표시소자에 관한 것으로서 특히, 면방전 방식의 플라즈마 표시소자에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plasma display device, and more particularly, to a surface discharge plasma display device.

일반적인 플라즈마 표시소자는 제1도에 도시된 바와 같이 격벽(B)에 의해 일정 간격을 유지하는 전면판(10)과 배면판(20)의 각 내면에 양극(A)과 음극(K)이 X-Y 매트릭스상으로 배치형성되는 구조를 가진다. 여기에서 상기 양극(A)은 일반적으로 투명한 ITO박막으로 이루어지는 바, 이는 음극(K)과 양극(A)의 사이에서 발생되는 가시광선의 진행경로상에 놓여 있기 때문인 것이다.In the general plasma display device, as shown in FIG. 1, the anode A and the cathode K are XY on each inner surface of the front plate 10 and the back plate 20 which are maintained at a predetermined interval by the partition B. As shown in FIG. It has a structure arranged in a matrix. The anode (A) is generally made of a transparent ITO thin film because it lies on the path of visible light generated between the cathode (K) and the anode (A).

이러한 종래 플라즈마 표시소자에 있어서의 단점은 상기한 음극(K)과 양극(A) 사이의 방전 영역으로부터 발생된 광이 상기한 바와 같이 투명한 양극(A)을 통과하기 때문에 광의 일부가 차단되어 휘도저하가 야기된다는 점인 바, 통상적으로 15 내지 25% 정도의 손실이 나타나게 된다.The disadvantage of the conventional plasma display device is that the light generated from the discharge region between the cathode K and the anode A passes through the transparent anode A as described above, so that a part of the light is blocked and the luminance decreases. Is caused, typically a loss on the order of 15 to 25%.

이를 해결하기 위하여는 상기한 양극의 소재인 ITO의 투명성을 향상시키는 방법과 이의 두께를 가능한 줄여주는 방법이 있는데, 전자의 방법은 소재의 특성에 관한 것이므로 개선의 여지가 극히 좁고, 후자의 경우는 박막 처리공정의 기술적 한계와 소재의 한정된 경도에 의해 제품의 불량률이 높아지게 되는 결점이 나타나게 된다.In order to solve this problem, there is a method of improving the transparency of ITO, which is the material of the anode, and a method of reducing the thickness thereof. The method of the former is about the characteristics of the material, so the room for improvement is extremely narrow. Due to the technical limitations of the thin film processing process and the limited hardness of the material, there is a drawback that the defect rate of the product is increased.

본 발명은 상기한 문제점을 해결하기 위한 것으로서 구조가 간단하고, 제조 생산성이 높은 플라즈마 표시소자를 제공함에 그 목적이 있다.An object of the present invention is to provide a plasma display device having a simple structure and high manufacturing productivity.

상기의 목적을 달성하기 위하여 본 발명은, 두매의 기판과, X-Y 매트릭스상으로 배열되는 음극과 양극, 화소간의 크로스 토오크를 방지하는 격벽을 갖춘 플라즈마 표시소자에 있어서, 상기 음극과 양극이 상기 배면판의 상면에 같이 형성되고, 이들의 교차부에는 이들간의 전기적 접촉을 방지하는 절연층이 형성되도록 하여 된 점에 그 특징이 있다.In order to achieve the above object, the present invention provides a plasma display device having two substrates and a partition wall for preventing cross-talk between a cathode and an anode and a pixel arranged in an XY matrix, wherein the cathode and the anode are the rear plate. It is formed on the upper surface of the same, and at the intersection thereof, it is characterized in that an insulating layer is formed to prevent electrical contact therebetween.

이하 첨부된 도면을 참조하면서 본 발명의 한 실시예를 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제2도에는 본 발명의 평면 방전형 플라즈마 표시소자가 도시되어 있다. 이 플라즈마 표시소자는 일정간격을 유지하는 전면판(10)과 배면판(20)중 전면판(10)에는 격벽(10)이 일정간격으로 배열 형성되고, 이에 대향되는 배면판(20)에는 상기 격벽(B)과 같은 방향으로 음극(K)이 배열되되, 격벽(B)에 대해 상호 교차되게 형성된다. 그리고 양극(A)은 음극(K)에 대해 직교되게 등간격으로 다수 배치된다. 이때에 이들 음극(K)과 양극(A)간의 교차부위의 중간에는 이들간의 전기적 접촉을 방지하는 절연층(I)가 개재된다.2 shows a planar discharge type plasma display device of the present invention. In the plasma display device, barrier ribs 10 are arranged on the front plate 10 of the front plate 10 and the back plate 20 at constant intervals, and the rear plate 20 opposite to the plasma display element is formed on the front plate 10. The cathodes K are arranged in the same direction as the partition wall B, and are formed to cross each other with respect to the partition wall B. In addition, a plurality of the anodes A are arranged at equal intervals orthogonal to the cathode K. At this time, the insulating layer I which prevents electrical contact therebetween is interposed in the middle of the intersection part between these cathodes K and anodes A. FIG.

이와 같은 본 발명의 플라즈마 표시소자는 일정 화상 신호를 담은 화상 신호가 순시 인가됨에 의해 화상을 플라즈마 방전으로 표시하게 되는데, 어느 음극과 양극이 선택되어 일정전위의 전압이 인가되면 음극과 양극의 일교점에서 방전이 야기되게 된다. 이때의 방전 양식은, 일교차부의 양극의 양가장자리부위와 그 하부의 음극의 양측을 통하여서 일어나는 양면 방전의 형태, 즉 배면판의 평면 방향으로의 방전의 형태(소위 평면 방전의 양식)을 갖추게 된다.Such a plasma display device of the present invention displays an image by plasma discharge when an image signal containing a predetermined image signal is instantaneously applied. When a cathode and an anode are selected and a voltage of a constant potential is applied, one intersection point of the cathode and the anode is applied. Will cause a discharge. The discharge mode at this time has a form of double-sided discharge that occurs through both edge portions of the anode of the cross section and both sides of the cathode of the lower portion, that is, the form of the discharge in the planar direction of the back plate (so-called planar discharge form).

이러한 본 발명의 플라즈마 표시소자는 그 구조가 독특하여 종래와는 다른 형태의 제조공정이 수반되어야 한다. 즉 전면판에 대하여는 격벽만이 형성되고, 배면판에는 소정의 성막(成膜) 공정을 통하여 음극과 양극이 형성되게 한다. 음극과 양극을 형성함에 있어서는 인쇄법등이 적용될 수 있는 바, 그 순서는 그 적층된 순서인 음극→절연층→양극의 순으로 이루어진다.Such a plasma display device of the present invention has a unique structure and requires a manufacturing process of a form different from the conventional one. In other words, only the partition wall is formed on the front plate, and the cathode and the anode are formed on the back plate through a predetermined film forming process. In forming the cathode and the anode, a printing method or the like can be applied, and the order thereof is in the order of the stacking order of cathode → insulation layer → anode.

이상에서와 같이 본 발명의 플라즈마 표시소자는 평면 방전의 형태를 가지도록 되어 있는 바, 제조가공이 간편하고, 양극도 음극과 같이 후막의 형태를 가질 수 있으므로 양극의 단락에 의한 제품의 불량률이 낮추어 질수 있게 된다. 더우기 그 두께가 두꺼워지므로 선저항이 현저히 저감되게 되는 바, 화면 전체에 있어서의 방전 특성이 고르게 분포되어 화질이 향상되게 된다.As described above, since the plasma display device of the present invention has a form of flat discharge, the manufacturing process is simple, and since the anode may have a thick film like the cathode, the defect rate of the product due to the short circuit of the anode is lowered. I can't. In addition, since the thickness becomes thick, the line resistance is significantly reduced, so that the discharge characteristics of the entire screen are evenly distributed and the image quality is improved.
