As domestic T F T- L C D panel manufacturers actively expand production scale, the demand for glass substrates has also increased. Basically, a TFT-LCD panel needs to use two glass substrates, which are respectively used as a bottom φ layer glass substrate (8), which is also called a glass, and a color filter (c〇i〇r fliter). A color filter having a color coating formed on the surface may also be referred to as a CF glass plate. At present, the manner of packaging and storing the aforementioned glass substrate can be divided into two types. The plain glass can be generally stored in the manner shown in "Fig. 1", and the plurality of glass sheets 10 are close to each other and stand in the side. The .: type is placed on a carrier 11, which is suitable for packaging unprocessed glass and has a large capacity for storage. CF glass plates, which have been formed with color filters, are damaged in order to avoid contact with each other and damage the color coating on the surface. Therefore, they must be stored and packaged in a special Tray 12 and stacked on top of each other. (as shown in Figure 2), and then removed one by one during unpacking. Therefore, the number of CF glass plates that can be stored in this φ packaging method is small, and the process of unpacking is also complicated and time-consuming.
