A display method, comprising:

• an image capturing step of capturing an image of a support surface of a support table included in at least one of the plurality of processing devices to perform processing on a processing object, the support surface being capable of supporting the processing object, the support surface being provided with a type mark including information on one of different types of processing performed by the at least one of the plurality of processing devices, the image being captured so as to include the type mark;
• an acquisition step of acquiring a captured image captured in the image capturing step;
• an identification step of identifying the one of the different types of processing included in the type mark in the captured image acquired in the acquisition step;
• a processing image acquisition step of acquiring a processing image, corresponding to the one of the different types of processing identified in the identification step, as an identified processing image;
• and
• a display step of displaying the captured image and the identified processing image in an overlapping manner, wherein
• the processing image is provided for each of the different types of processing to be performed on the processing object, the plurality of processing images for the respective types of processing being stored, and
