摘要： PURPOSE:To enable color display with high brightness, high light emission efficiency, and high precision and make the device larger by boring a plurality of holes for forming discharge space, and by making a plurality of green sheets through a baking process. CONSTITUTION:An intermediate layer 13 of a plasma display panel(PDP) is furnished between a front plate 6 of glass and a back plate 7, and holes 151-155 for forming the discharge space are bored in each of them, and a plurality of green sheets 141-145 laminated and fastened are baked. Each green sheet 141-145 is prepared by the doctor blade method, etc., from a mixed slip of ceramic fine powder and organic binder, etc., into a thin sheet and is equipped with sample processing property. This permits easy boring of the holes 151-155 for forming the discharge space, which can be made wide.

摘要： PURPOSE:To upgrade luminous efficiency and luminous brightness by standing discharge surfaces of discharge electrodes nearly at a right angle to a substrate surface so that discharge spacing is enlarged. CONSTITUTION:Excited emission of ultraviolet rays is generated inside a dis charge space 9 by discharge between electrodes 2 and 4 disposed on a substrate 1, and subsequently a phospher 8 is excited to become luminous. In this case, a product Pd of a discharge gas pressure P and an interval (d) between the discharge electrodes is fixedly related to a discharge starting voltage V by a Paschen's law, where the pressure P needs to be larger as the interval (d) becomes smaller and so luminous brightness and luminous efficiency are deterio rated. The electrodes 2 and 4 are disposed nearly at a right angle to the sub strate 1 and they are made approximately 100 mum to 200 mum in height and they can be made to face each other at a sufficient interval. Hence, application of a required voltage enables the emission of the light excellent in luminous efficiency and luminous brightness.

摘要： PURPOSE:To heighten definition in color display without causing the deterioration of luminous brightness or causing the nonuniformity of the color display, by mutually stacking, red-green-blue element outputting discharge cells which form the display area of a color displaying unit pixel in arbitrary sequence in a direction vertical to a screen. CONSTITUTION:Green-red-blue element discharge cells 10g, 10r, 10b are mutually stacked in a direction vertical to the screen 15 of a frontal faceplate 12 to form a color displaying unit pixel 10. Thus, the display area of the color displaying unit pixel can be reduced to one third or one quarter the conventional embodiment for permitting to treble or quadruple the definition of color display even if electric discharge is not attenuated through the process of equalizing the display area of the pixel consisting of the red-green-blue element discharge cells to that of the conventional embodiment.

摘要： PURPOSE:To increase finess of a displaying image and to upgrade luminous efficiency and luminous brightness by juxtaposing the desired number of electrodes which have discharge surfaces standing almost perpendicularly to a surface of a substrate so that discharge is generated between electrodes adjacent to each other. CONSTITUTION:Discharge electrodes 2a and 2b and the like are juxtaposed at desired intervals on a substrate 1, and their respective discharge surfaces 11 and 12 are stood perpendicularly to the substrate 1 and discharge is generated between the adjacent electrodes. An access electrode 13 is interposed between the electrodes 2a and 2b, and its connecting line part 14 is formed to cross the electrodes 2a and 2b. Besides, a regulation electrode 15 is formed according as needed. Thus, one electrode is used jointly for two cells, so that finess of a displaying image is increased. Moreover, since a discharge space is made large, luminous efficiency and luminous brightness is upgraded.

摘要： PURPOSE:To promote emission of secondary electrons and enhance the brightness and efficiency in light emission by forming an inter-cell barrier for prevention of color cross-talk in correspondence to a group of cells of individual discharge, and by forming an oxide film on the wall surface of this inter-cell barrier. CONSTITUTION:When sequential scanning pulses are impressed on either of the X electrode group and Y electrode group, for ex. Xn, Xn+1,..., while indication pulses on the other electrode group Ym, Ym+1,..., discharge takes place between for ex. Xm electrode with discharge voltage impressed and individual discharge electrodes 6, 6... of the Ym, Ym+1,..., electrodes, and corresponding discharge cells S, S,... make discharge light emission. Provision of an inter-cell barrier 8 raises the discharge voltage with color cross-talk prevented. A MgO film 9 is formed. This improves the secondary electron emitting efficiency and sinks the discharge voltage. which smoothens the drive and increases the brightness and efficiency in light emission.

摘要： PURPOSE:To reduce the time of evacuating the inside of a plasma display panel (PDP) or enclosing a discharge gas in the PUP, and to obtain a high luminous brightness, by forming a gap for ventilation between the top end surfaces of a fence body group and the opposite inner surface of a rear side plate, and spreading a phosphor on the side surfaces facing the display discharge cells of the fence body group. CONSTITUTION:Since a gap 8 for ventilation is formed between the top end surfaces of a fence body group 6m-1, 6m,...which are projected from the opposing inner surface of a front side plate 1, and the opposite inner surface of a rear side plate 2, the fence body group 6m-1, 6m,... never disturb the flow of gas. Moreover, since a phosphor is spread on the side surfaces facing the display discharge cells Dl, m of the fence body group 6m-1, 6m,..., the luminous area of the phosphor depending on the discharge is increased. Therefore, a high luminous brightness can be obtained,as well as the time to evacuate the PDP and to enclose a discharge gas therein can be reduced.
