Claim 10:
11. A stamp for nano imprinting, the stamp comprising:
a base substrate having a plane defined in a first direction and a second direction crossing each other; and
a pattern group comprising a plurality of nano patterns disposed on the base substrate and spaced apart from each other in the first direction and each extending in the second direction,
wherein the pattern group comprises a first pattern group and a second pattern group, each of the first pattern group and the second pattern group comprises a first pattern part and a second pattern part that are arranged to be spaced apart from each other in the first direction and each has a rectangular shape defined along the first direction and the second direction,
wherein the first pattern part of the first pattern group, the first pattern part of the second pattern group, the second pattern part of the first pattern group, and the second pattern part of the second pattern group are disposed to be arranged adjacent to each other in a linear sequential order in the first direction,
wherein, in the second direction, a first length of the nano patterns of the first pattern part of the first pattern group are different from a second length of the nano patterns of the second pattern part of the first pattern group, and
wherein, in the second direction, a third length of the nano patterns of the first pattern part of the second pattern group are different from a fourth length of the nano patterns of the second pattern part of the second pattern group.
