Cut as a board (Step U2). Thereafter, the process proceeds to an additional process, where the glass is cut into the size of the plate glass for the display substrate, and the end face is chamfered (Step U3). Polish the surface (Step U4). In the inspection process, the polished plate glass is inspected for quality such as the presence of flaws and bubbles that contain scratches (Step U5). If polishing (Step U4) is not performed, inspection (Step U5) is performed immediately after cutting and chamfering (Step U3).
- step U6 the quality of the display substrate plate glass (hereinafter simply referred to as plate glass) is determined (step U6).

- the entire glass surface is polished by a polishing machine by the depth.
- the entire surface of the plate glass is re-polished with the same polishing machine as in the polishing step (step U4). If polishing is not performed for flatness of the surface of the glass sheet, it is polished for correction for the first time.
- the plate glass for a display substrate is almost free from scratches on the surface of the plate glass and internal bubbles. There is a need for flat glass with almost no defects. Because of this requirement, for example, there are defects such as micro-scratches, and therefore, polishing the entire surface of the plate glass as a correction product for correction requires man-hours and increases the cost of poor production efficiency. Also, due to some drawbacks, discarding the entire product is wasteful and reduces yield.
- Patent Document 1 discloses a liquid crystal panel in which an identification mark is provided on a glass substrate and a method for identifying a liquid crystal panel substrate.
- n identification marks are provided at regular intervals at predetermined positions outside the display area of the liquid crystal panel, and alignment is performed when the liquid crystal is sandwiched between two substrates, the first substrate and the second substrate. It is easy to do.
- the identification method described in Patent Document 1 uses the identification mark to align the substrate type, front / back, and substrates when manufacturing the liquid crystal panel, and does not relate to the quality of the substrate! /.

- the usage area of the plate glass used by the customer is compared with the defect information by the mark (step ⁇ 5) to determine how many defects are in the usage area (step ⁇ 6). For example, even a plate glass having a defect can be used as it is when the defect is in a non-use area, so that resources are not wasted. As a result, if there are no defects or the defects and quality that can be used, plate glass is used (step ⁇ ⁇ ⁇ ⁇ 7). On the other hand, if there is a defect, it is determined whether it can be corrected (step ⁇ 8). If it can be corrected, it is used after correction (step ⁇ 9, ⁇ 10). If it is not possible, it is discarded or recycled (step Tl l).

- Step T7 it is determined to what extent the application area has defects (Step T6), so that the glass substrate is used (Step T7) or modified (Step T9) or discarded and recycled (Step Tl 1). ).
- Step T9 it is determined to what extent the application area has defects
- Step T9 modified
- a mark 2 indicating the type, position, degree, etc. of the defect is formed at a predetermined position of the peripheral portion S of the glass sheet 1 (in the figure, at the upper right position on the surface of the glass sheet).
- This mark 2 is preferably formed on the periphery of the plate glass 1 with a width of 5 to: LO mm and a length of several centimeters as shown in the figure. Good.

- 4 is a defect that bubbles exist on the surface
- 5 is a defect that bubbles exist inside.
- the sheet glass 1 on which the mark 2 related to these defects 3, 4 and 5 is formed is packed and shipped from the shipping source or the previous process to the shipping destination (customer) or the subsequent process.
- the display areas A ′ to F ′ of the glass substrate are compared with the defect information.
- the glass substrates in areas A to D are used as defect-free glass substrates because they use areas without defects. Since the glass substrate in the region E has the surface bubbles 4 that can be modified, a modification for removing the bubbles 4 is added in a later step.
- the glass substrate in area F has bubbles 5 inside, but if it can be used as a lower grade product with a lower quality grade, use it as a lower grade.
- the scratch 3 is in the non-use area E ", the customer is not affected by the manufacturing process due to this defect. Thus, the customer can manage based on the defect information obtained from the mark 2.
- plate glass containing defects can be used effectively, and plate glass for display substrates can be efficiently manufactured even in the plate glass manufacturing process, which is divided into 6 parts in FIG.
- the pattern to be divided differs depending on the size of the glass sheet and the size of the display product. Therefore, the number of pieces to be divided is not limited. .
- the above is the force described for the plate glass for a display substrate. If the above polishing is replaced with other processing means, in addition to general plate glass such as plate glass for buildings and automotive glass, ceramic plate, resin plate, metal plate, etc. It is also effective as a method for managing the separation of plate-like bodies. However, considering that the plate-like body can be used after being cut into glass substrates of various dimensions, this is particularly effective for the method for separating and managing the plate glass for display substrates.
- the present invention can be applied to a method for separating and managing plate-like bodies in the production of plate-like bodies.
