Abstract: Provided are a lighting system, a backlight unit and a 3D image display apparatus including the backlight unit. The backlight unit includes: a lighting system configured to selectively output collimated light and diverging light, a diffraction device, and a light guide plate configured to guide the collimated light and the diverging light from the lighting system to the diffraction device. An exit direction of the collimated light from the diffraction device depends on at least one of an angle of incidence of the collimated light and the wavelength of the collimated light.

Abstract: A patterning method using an imprint mold, to form an imprinted pattern structure, includes providing a resist layer from which the pattern structure will be formed, performing a first imprint process on a first area of the resist layer by using the imprint mold to form a first pattern of the pattern structure through deformation of the resist layer in the first area, and performing a second imprint process on a second area of the resist layer by using the imprint mold to form a second pattern of the pattern structure through deformation of the resist layer in the second area. The first and second areas are overlapped with each other in a third area of the resist layer, and the performing the second imprint process deforms a first portion of the first pattern in the third area to form the second pattern.
