    Abstract: A polarizing assembly includes a polarizing substrate which transmits a specific linearly-polarized light of a light incident thereto and a patterned retarder. The patterned retarder includes first retarder patterns which convert the light for a left-eye image transmitted by the polarizing substrate into a first polarized light and second retarder patterns which convert the light for a right-eye image transmitted by the polarizing substrate into a second polarized light. The first retarder patterns have a light axis substantially perpendicular to a light axis of the second retarder patterns. The polarizing substrate includes a polarizing plate which transmits the specific linearly-polarized light of the light incident thereto and a glass fiber reinforced plastic substrate which is attached to the polarizing plate.
