Abstract
An image display apparatus according to an embodiment of the present technology includes a polarizer, a polarization conversion element, and a ¼ wave plate. The polarizer causes to transmit linearly polarized light having a predetermined polarization direction. The polarization conversion element converts a polarization state of the linearly polarized light transmitted through the polarizer and emits the light as light in a non-polarized state. The ¼ wave plate is arranged on an optical path of the light in the non-polarized state emitted from the polarization conversion element.
