Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] When making a display substrate motherboard, in order to make any pattern on the display substrate motherboard be formed in a predetermined position, it is necessary to use a The alignment mark pattern for making this pattern is aligned with the mark pattern on the mask plate (Mask), and then exposed. Based on this, the display substrate motherboard should be provided with an alignment mark pattern for pattern making.

[0032]In addition, after the dis...

Abstract

The embodiment of the invention provides a substrate mother board for display, a display panel mother board and a preparation method of a display panel, and relates to the technical field of display.The problem that the cleaning liquid corrodes an alignment marking pattern on the edge of the display panel mother board when the display panel mother board is cleaned can be solved. The substrate mother board for display comprises: a first alignment marking pattern arranged on a first surface of the substrate; wherein the substrate mother board for display further comprises a transparent protection pattern, wherein the protection pattern at least covers the first alignment marking pattern located on the edge of the first surface; the first alignment marking pattern comprises a first sub-alignment marking pattern and / or a second sub-alignment marking pattern, the first sub-alignment marking pattern is used for forming alignment exposure of the pattern on a second surface of the substrate,and the second sub-alignment marking pattern is used for cutting alignment; and the first surface and the second surface are two opposite surfaces of the substrate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate motherboard, a display panel motherboard and a method for preparing a display panel. Background technique [0002] At present, during the production process of the display panel motherboard, the surface of the display panel motherboard often produces wheel prints and dirt. This is because the black matrix pattern and When color photoresist patterns are applied, the back of the color film substrate will inevitably contact the machine and the transfer wheel, resulting in more wheel marks and dirt on the back of the color film substrate. After forming the display panel mother board, the display panel mother board There will be wheel marks and dirt on the surface of the board. Therefore, after the display panel motherboard is fabricated, the surface of the display panel motherboard needs to be cleaned before the touch layer is fabricated. [0003] However, when...
