Abstract: A cover layer manufacturing method includes: a first applying process, which forms a first cover layer on a rear surface of a first display panel using a first mask in an applying unit; a first cleaning process, which cleans a second mask in a cleaning unit; a rotating process, which changes a position of the first mask and a position of the second mask using a rotation driver; a second applying process, which forms a second cover layer on a rear surface of a second display panel using the second mask in the applying unit; and a second cleaning process, which cleans the first mask in the cleaning unit. The first applying process and the first cleaning process are substantially simultaneously performed, and the second applying process and the second cleaning process are substantially simultaneously performed.
