Image display device

A method for displaying different views of an image comprising the acts of:

• forming an image from a plurality of separately addressable pixels in a display panel, the pixels being grouped such that a first group of the pixels is configured to provide emergent light in a first polarisation state, and a second group of the pixels is configured to provide emergent light in a second polarisation state;
• partly occluding the emergent light by means of a barrier layer in optical association the display panel, the barrier layer having a first plurality of regions for passing light in one of said first or second polarisation states, a second plurality of regions for passing light in the other of said first or second polarisation states and a third plurality of regions for occluding said emergent light;
• the barrier layer being disposed such that the first and second regions of the barrier layer are respectively registered with the first and second groups of pixels.
