IMAGE DISPLAY APPARATUS AND IMAGE DISPLAY UNIT

Abstract:

An image display apparatus according to an embodiment of the present technology includes: a light emission unit; and a polarization conversion element. The light emission unit emits image light. The polarization conversion element has an incident surface, converts a polarization state of the image light that enters the incident surface, emits the converted light as image light in an unpolarized state, and is configured such that conversion properties of the polarization state are non-uniform in the incident surface. As a result, it is possible to sufficiently depolarize the image light and display a high-quality image. In addition, it is possible to reduce uneven polarization and speckles.
