ABSTRACT:
An autostereoscopic display having an improved 2D/3D mode switchable structure, including a display device to display an image, and a parallax barrier unit to transmit all incident light in a 2D mode and to separate a left-eye image and a right-eye image by forming a barrier in a 3D mode. The parallax barrier unit includes a polarizer to transmit light having a predetermined polarizer polarization direction, a first plane array including first and second birefringent elements, which change a polarization direction of light transmitted through the polarizer into a first direction and a second direction opposite to the first direction, respectively, and a second plane array including third and fourth birefringent elements, which change a polarization direction of light transmitted through the first plane array into a third direction and a fourth direction, that is opposite from the third direction, respectively.
