   wherein, in a state in which the display panel is held in the holding recess, a top tier tray having a shape of the packaging tray is stacked above the packaging tray, and a bottom tier tray having the shape of the packaging tray is stacked below the packaging tray,   the supporting foot includes a first contact surface that is in contact with the tray supporting portion of the bottom tier tray,   the panel pressing portion includes a second contact surface that is in contact with the display panel held in the bottom tier tray, and   the tray supporting portion includes a third contact surface that is in contact with the first contact surface of the top tier tray.   
     
     
         2 . The packaging tray according to  claim 1 ,
 wherein the panel supporting portion is disposed at a position where the panel supporting portion comes into contact with a peripheral portion of the display panel from below, and   wherein the panel pressing portion is disposed at a position where the panel pressing portion comes into contact with the peripheral portion of the display panel from above.   
     
     
         3 . The packaging tray according to  claim 2 , wherein the second contact surface is provided so as to incline with respect to the first contact surface and comes into contact with an upper corner of the peripheral portion of the display panel. 
     
     
         4 . The packaging tray according to  claim 2 ,
 wherein the panel pressing portion further includes a first step portion provided between the first contact surface and the second contact surface, and   wherein the second contact surface comes into contact with an upper surface of the peripheral portion of the display panel.   
     
     
         5 . The packaging tray according to  claim 4 ,
 wherein the supporting foot further includes a side wall surface rising from the second contact surface toward the panel supporting portion, and   wherein a junction of the second contact surface and the side wall surface is rounded into a curved surface.   
     
     
         6 . The packaging tray according to  claim 4 , wherein the panel pressing portion further includes a noncontact surface that is continuous from the second contact surface and that does not come into contact with the display panel and a second step portion that is provided between the second contact surface and the noncontact surface. 
     
     
         7 . The packaging tray according to  claim 1 ,
 wherein a shape of the supporting foot as seen in a normal direction of the bottom plate is a rectangle, and   wherein corners of the rectangle that is the shape of the supporting foot are rounded into curved surfaces.   
     
     
         8 . The packaging tray according to  claim 1 , wherein an outer dimension of an upper side of the tray supporting portion is relatively large, and an outer dimension of a lower side of the tray supporting portion is relatively small.
