본 발명은 플라즈마 표시소자에 관한 것으로서, 특히 화소간의 크로스토크를 방지하는 격벽의 구조가 개량된 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 plasma display device having an improved structure of a partition wall for preventing crosstalk between pixels.

일반적인 직류형 플라즈마 표시소자(이하 PDP라 칭함)는 제1도에 도시된 바와 같이, 평행한 두 기판(10)(20)의 각 내면에 다수의 양극(A)과 음극(K)이 X-Y 매트릭스상으로 배열형성된 것으로서, 상부측 각 양극(A)의 사이에는 크로스토크를 방지하기 위한 격벽(barrier rib; B)이 소정높이로 형성되는 구조를 가진다. 이러한 PDP는 상기한 바와 같이 상기 양극(A)과 음극(K)들이 방전가스가 채워지는 내측 공간부에 노출되어 있어서, 종횡의 각 양극과 음극에 순시 인가되는 직류전압에 의해 노출된 상하 음극(K)과 양극(A)들의 사이 즉 하나의 화소(PIXEL)에서 직류 방전이 일어나게 된다.A general DC plasma display device (hereinafter referred to as a PDP) has a plurality of anodes A and cathodes K on an inner surface of two parallel substrates 10 and 20, as shown in FIG. It is arranged in a phase, and has a structure in which a barrier rib (B) for preventing crosstalk is formed at a predetermined height between the upper anodes (A). As described above, the PDP is exposed to the inner space where the anode A and the cathode K are filled with the discharge gas, so that the vertical cathode exposed by the DC voltage instantaneously applied to each of the vertical and horizontal anodes and cathodes ( DC discharge occurs between K) and the anode A, that is, in one pixel PIXEL.

이와 같은 종래 PDP에 있어서 상기의 격벽은 전기한 바와 같이 화소간의 크로스토크를 방지하기 위한 것으로서, 전면판 또는 배면판에 일괄적으로 형성되도록 되어 있다. 그러나 이러한 종래의 PDP에 있어서는 상기한 바와 같이 격벽이 전면판 또는 배면판에만 형성되도록 되어 있기 때문에 제조가공이 매우 까다롭고, 그 불량률도 매우 높은 단점을 가진다. 이는 일측판에 대한 격벽의 가공시 이에 수반되는 제조 공정중 성막기술상의 한계가 있기 때문인 것이다. 더우기 고해상도의 PDP의 경우 화소가 극히 작아지고 이에 따라 격벽간 간격도 이에 대응되게 좁히는 데에는 많은 어려움이 뒤따르고 결과적으로 제품의 설계조건에 실제 적용하는데에 있어서 무리가 있고 이와 같은 경우, 높은 불량률을 감수하여야만 하는 것이다.In such a conventional PDP, the partition wall is used to prevent crosstalk between pixels as described above, and is formed collectively on the front plate or the back plate. However, in the conventional PDP, since the partition wall is formed only on the front plate or the back plate as described above, the manufacturing process is very difficult and the defect rate is also very high. This is because there is a limitation in the film forming technology during the manufacturing process accompanying the partition wall for one side plate. Furthermore, in the case of high-resolution PDP, the pixel becomes extremely small and accordingly, there are many difficulties in narrowing the space between the bulkheads correspondingly, and as a result, it is difficult to actually apply it to the design conditions of the product. It must be done.

본 발명은 제품의 불량률을 저감할 수 있도록 그 구조가 개량된 플라즈마 표시소자를 제공함에 그 목적이 있다.An object of the present invention is to provide a plasma display device whose structure is improved to reduce the defective rate of the product.

상기의 목적을 달성하기 위하여 본 발명은, 두매의 기판과, 이들 각 면에 X-Y 매트릭스상으로 배열형성되는 다수의 스트라이프형 양극과 음극과 각 화소간의 크로스토오크를 방지하는 격벽을 갖춘 플라즈마 표시소자에 있어서, 상기 전면판과 배면판의 내면에 상기 격벽을 교호적으로 배치 형성하여서 된 점에 그 특징이 있다.In order to achieve the above object, the present invention is directed to a plasma display device having two substrates, a plurality of stripe type anodes and cathodes arranged on each surface thereof in an XY matrix, and partition walls for preventing crosstalk between the pixels. The feature is that the partitions are alternately arranged on the inner surfaces of the front plate and the back plate.

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

우선 본 발명의 플라즈마 표시소자는 제2도에 도시된 바와 같은 구조를 가진다.First, the plasma display device of the present invention has a structure as shown in FIG.

일정간격을 유지하는 전면판(10)과 배면판(20)에 다수 양극(A)과 단위 음극(K)이 X-Y 매트릭스상으로 교차 배열되며, 상기 양극(A)득의 사이에는 격벽(B)이 일정높이로 형성된다. 이때에 상기 격벽(B)은 본 발명의 특징적요소를 가지는 것으로서 상기 전면판(10)과 배면판(20)에 분산배치되되, 상호 교호적으로 형성된다. 이때에 배치방식은 전면판(10)과 배면판(20)에 번갈아가며 형성하는 방식과, 일정갯수의 격벽을 한 단위로 하여 단위별로 번갈아가며 형성하는 방식으로 나뉠수도 있는 바, 실제적으로 전자(前者)의 방식이 채용됨이 바람직하다.A plurality of anodes (A) and a unit cathode (K) are intersected and arranged in an XY matrix on the front plate (10) and the back plate (20) maintaining a constant interval, and the partition (B) is formed between the gains of the anode (A). It is formed at a certain height. At this time, the partition (B) is distributed to the front plate 10 and the back plate 20 as having the characteristic elements of the present invention, are formed alternately. At this time, the arrangement method may be divided into a method of alternately forming the front plate 10 and the rear plate 20 and a method of alternately forming a predetermined number of partitions by one unit, in fact the electron ( The former method is preferably employed.

이와 같은 구조를 가지는 본 발명의 플라즈마 표시소자는 전면판(10)과 배면판(20)에 대해 격벽이 분산배치되는 구조를 가지므로 격벽을 형성하는데에 있어서의 가공상 부담이 저감되게 된다. 따라서 격벽간의 간격이 종래에 비해 평균 2배가 확장되는 결과를 나타내게 되므로 보다 고정세화된 구조를 가질 수 있게 된다. 상기와 같은 본 발명의 플라즈마 표시소자는 구조적으로 불량률이 크게 저감될 수 있도록 되어 그 제조생산성이 높은 장점을 가지는 바, 일반적인 화상 표시수단을 위한 범용의 화상 표시소자로서 보다는 매우 조밀한 화소를 가지는 HDTV용 화상 표시소자로 적합한 것이다.The plasma display device of the present invention having such a structure has a structure in which the partition walls are distributedly disposed with respect to the front plate 10 and the back plate 20, thereby reducing the processing burden in forming the partition walls. As a result, the spacing between the partition walls is increased by an average of 2 times as compared with the prior art, and thus the structure can have a more precise structure. As described above, the plasma display device of the present invention has a merit that the defect rate can be greatly reduced, and thus the manufacturing productivity is high. HDTV having a very dense pixel than a general-purpose image display device for general image display means. It is suitable as an image display element.
