Problems solved by technology

[0018] However, if a high-definition grid-like barrier rib having a main barrier rib width of 40 μm or less is to be produced by the method using the above-mentioned glass paste, there is a problem that the main barrier rib and the auxiliary barrier rib are compressed because the organic component is removed and shrinks during firing. The height of the intersection will be increased, and the height of the main barrier rib will be reduced between the intersection and the intersection, that is, the part that separates the discharge space of the adjacent display unit (hereinafter referred to as the partition)
[0020] In this way, if the height of the main barrier rib increases at the intersection with the auxiliary barrier rib and decreases at the partition, it will not only cause color mixing when forming the phosphor layer, but also cannot fully perform the function of the main barrier rib separating the discharge space. , which becomes the main reason for deteriorating the display characteristics of the PDP panel

Embodiment 1

[0214] Address electrodes were fabricated on a glass substrate PD200 (size: 964×570 mm) with photosensitive silver paste. The photosensitive silver paste was coated, dried, exposed, developed and fired to form address electrodes with a line width of 20 μm, a thickness of 3 μm, and a pitch of 100 μm.

[0215] 0080

[0216] Next, 60% by weight of low-melting glass powder containing 75% by weight of bismuth oxide, 10% by weight of titanium oxide powder with an average particle size of 0.3 μm, 15% by weight of ethyl cellulose, and 15% by weight of terpineol were mixed to obtain glass paste. Then, screen printing is used to coat the glass paste with a thickness of 20 μm to cover the bus bar electrodes of the display part, and then bake at 570° C. for 15 minutes to form a dielectric layer.

[0217] 0081

[0218] Coat the photosensitive paste on the dielectric layer. The photosensitive paste is composed of glass powder and organic components containing photosensitive components. ...

Embodiment 2~5、 comparative example 1~3

[0227] Adopting and implementing In the same manner as in Example 1, a member for a plasma display was obtained. Table 1 shows properties of the obtained member for a plasma display. In Example 2, Wb / Wa was 2.5, and the height difference of the main barrier rib was slightly large at 5 μm, but there was no problem in use. The Wb / Wa of Examples 3 and 4 are 1.3, the Wb / Wa of Example 5 is 1.5, and the Wb / Wa of Example 6 is 1.4. The height differences of the respective main barrier ribs are 1 μm, 4 μm, 5 μm, and 2 μm, respectively. In Examples 4 and 5, since Ha2-Hb is large, the height difference of the main barrier ribs is slightly larger, but there is no problem in use. In the members for plasma displays of Comparative Examples 1, 2, and 3, Wb / Wa was less than 1.2, and there was a problem that the height of the main barrier rib in the partition portion was low.

Abstract

Provided is a member for plasma display having a lattice-like partition consisting of at least a main partition and an auxiliary partition formed on a substrate in which the height at the partition of the main partition is prevented from becoming smaller than the height at an intersection even when a high precision lattice-like partition where the width at the top of the main partition becomes 40 mu m or less is provided, and the problem of erroneous emission of light from a cell is eliminated. [MEANS FOR SOLVING PROBLEMS] In a structure where the width at the top of the main partition is 40 [mu]m or less and the main and auxiliary partitions are arranged in lattice, the height at the intersection of the main and auxiliary partitions is set to be 0-2 mu smaller than the height at the main partition by setting the relation between the width (Wa) at the top of the main partition and the width (Wb) at the top of the auxiliary partition to satisfy Wa / Wb>=1.2.

Description

technical field [0001] 0001 [0002] The present invention relates to a member for a plasma display and a manufacturing method thereof. Background technique [0003] 0002 [0004] Plasma display panels (hereinafter referred to as PDPs) are attracting attention as displays that can be used for thin and large televisions. One example of a PDP structure is formed by forming a plurality of paired sustain electrodes on a glass substrate on the front panel side as a display surface using materials such as silver, chromium, aluminum, and nickel. Then, to cover the sustain electrodes, a dielectric layer mainly composed of glass is formed to a thickness of 20 to 50 μm, and an MgO layer is formed to cover the dielectric layer. On the other hand, a plurality of address electrodes are formed in substantially stripes on the glass substrate on the rear panel side, and a dielectric layer mainly composed of glass is formed to cover the address electrodes. Barriers for isolating the disc...
