Also, the second height difference HG2 may be larger than the first height difference HG1. Thereby, due to vibration or impact generated when the stacking tray module 1000 is packed or transported, contact between the lens 55 of the second substrate 52 and the base 210 of the second stacking tray 200 Damage can be prevented.

Here, the first height difference HG1 is preferably 3 mm or more, and the second height difference HG2 is preferably 4 mm or more. However, these numerical limitations are only for explanation of one embodiment, and can be changed to various values according to the thickness HL of the lens 55. [ On the other hand, an upper limit value of about 10% can be set in proportion to the lower limit value, thereby preventing an increase in tray height more than necessary.

The height H2 of the first protrusion 130 from the first support 110 in the first stacking tray 100 is greater than the thickness HL of the lens 55, The upper surface of the second substrate 52 abuts against the lower surface of the base 210 of the second stacking tray 200 so that the vibration of the lens 55 of the second substrate 52, 2 can be prevented from being damaged by the contact occurring between the bases 210 of the stacking tray 200.

The depth D1 of the second protrusion 140 is smaller than the height H2 of the first protrusion 130 from the first supporter 110 so that the second protrusion 130 When the tray 200 is stacked, the plurality of second projections 240 of the second stacking tray 200 are inserted between the spacing spaces of the plurality of first projections 130 of the first stacking tray 100, The lower surfaces of the plurality of second protrusions 240 of the stacking tray 200 are spaced apart from the upper surface of the first support portion 120 of the first stacking tray 100.

The pair of substrates 50 are stacked in a spaced space between the lower surface of the second protrusion 240 of the second stacking tray 200 and the upper surface of the first support portion 120 of the first stacking tray 100 The position can be fixed.
