It relates to a panel conveying apparatus.

In general, a flat panel display includes a liquid crystal display (LCD) using liquid crystal, a plasma display (PDP) using plasma, an organic light emitting display (OLED) using an organic light emitting element, and the like.

The flat panel display basically includes a panel displaying an image. The panel is manufactured by repeatedly performing various processing processes such as a deposition process, an etching process, a photolithography process, a cleaning process, and an inspection process on a substrate using a substrate having a large area such as a glass substrate as a mother substrate.

Among the treatment processes, in particular, the cleaning process is repeatedly performed after each process. For example, after the etching process, the cleaning process is performed on the substrate which has undergone the etching process in order to clean the impurities remaining on the substrate and particles such as chemicals used for etching.

In particular, the adhesion of particles has a large effect on the yield of the device.

Therefore, particles must be removed to secure the reliability before and after the process and to improve the yield. As the technology advances, the cleaning process also requires technical development as the panel is enlarged and the pattern is made finer.
