Abstract: A polarization plate is provided for use between a light source and a display panel, where the light source is configured to emit light having a plurality of planes of polarization and the display panel is configured to have a predetermined polarization axis. The plate includes a repolarization region and a prepolarization region. The repolarization region is configured to diffuse and to depolarize or rotate at least one plane of polarization of the light passing therethrough. The prepolarization region is disposed adjacent to and in contact with the repolarization region. The prepolarization region is configured to be substantially nonabsorbent, to allow passage of light having a plane of polarization that is substantially aligned with the predetermined polarization axis, and to prevent passage of light having a plane of polarization that is not substantially aligned with the predetermined polarization axis. In another embodiment, an interface is provided between the regions.
