A head-up display includes a first panel, a second panel, and an optical system. The first panel includes first subpixels arranged at a first pitch in a parallax direction, in which direction binocular parallax is provided to user's eyes. The second panel includes second subpixels arranged at a second pitch in the parallax direction. The second panel is placed along the first panel. The second panel is configured to produce, based on an image displayed on the first panel, a parallax image for providing binocular parallax to the user's eyes. The optical system enables the parallax image to be provided in enlarged dimension to the user's eyes. The first pitch and the second pitch are equal to each other.

An optical device (EPE1) comprises a waveguide plate (SUB1) comprising an in-coupling element (DOE1), a first expander element (DOE2a), a second expander element (DOE2b) and an out-coupling element (DOE3), wherein the out-coupling element (DOE3) is arranged to form combined output light (OUT1) by combining the first output light (OB3a) with the second output light (OB3b),wherein the in-coupling element (DOE1) has a first grating period (d.sub.1a) for forming the first guided light (B1a), and wherein the in-coupling element (DOE1) has a second different grating period (d.sub.1b) for forming the second guided light (B1b),wherein the optical device (EPE1) comprises a first spectral filter region (C2a) to prevent coupling of red light from the in-coupling element (DOE1) to the out-coupling element (DOE3) via the first expander element (DOE2a).The optical device (EPE1) can display a color image with an extended field of view.

The invention relates to a light modulation device for a display for representing two- and/or three-dimensional image content or image sequences. The light modulation device comprises a light modulator and a controller. The phase and/or the amplitude of a light wave field, which is substantially collimated, can be varied by means of the light modulator depending on the location of the light modulator. The light modulator can be actuated by means of the control device. According to the invention, in the direction of propagation of the light wave field, at least one diffracting unit is arranged downstream of the light modulator. The diffracting unit has a variable diffracting structure. By means of the diffracting structure, the light wave field varied by the light modulator can be diffracted in a variable and predeterminable manner. Further, the present invention relates to a display and a method for producing a light modulation device.
