Problems solved by technology

[0018] Afterwards, a cross-shaped relief is formed at the position where the Align Mark is formed, and the a, b, c, d, e, f, g, h, and i regions are adjusted step by step to remove the ITO film to form the Align Mark of the relief. .However, if the alignment mark is formed by such a method, the etching operation of the alignment mark is complicated, and it takes time to move multiple times according to a certain distance
[0019] In addition, the error caused by multiple movements accumulates and the position of the Align Mark cannot be accurate, which seriously reduces the characteristics of the plasma display panel.
[0020] Moreover, when the shape of the Align Mark needs to be changed, the Align Mark formed by Yang engraving is not easy to modify

Example Embodiment

[0036] Hereinafter, the present invention will be described in detail with reference to the drawings.

[0037] Figure 5 shows the position where the Align Mark is formed.

[0038] As shown in FIG. 5, the Align Mark according to the present invention is formed on the non-printing area 510 of the substrate 500 coated with the photosensitive film. Here, the photosensitive film is preferably composed of an indium oxide film ITO and Indium Tin Oxide.

[0039] At this time, more than one inscribed Align Mark is formed in the non-printing area, such as the symbols B, C, D, and E.

[0040] According to the present invention, the specific method of forming the Align Mark in the non-printing area 510 is shown in FIG. 6.

[0041] 6 is a schematic diagram of a method for forming an Align Mark of a plasma display panel according to the present invention.

[0042] As shown in FIG. 6, the Align Mark forming method of the plasma display panel according to the present invention is to form at least on

Abstract

The invention discloses a location mark forming method for plasma panel. It forms at lest one negative carve mark on the non-printing area of the basal board of daubing light sensitive layer, and it forms at the corner part of the area. After location mark daubing, and the moving times of daubing decreasing, the Align Mark would be accurately formed and the feature of plasma panel would be effectively improved. The alteration of the state of Align Mark would be easier.
