A device for a head's up display comprises a picture generating unit; a projector optics; and a combiner. The combiner comprises a substrate made of optically transparent material and micro-optical structures arranged in a discrete array. The picture generating unit is arranged to deliver a beam of light, containing an image, to the projector optics. The projector optics and the combiner are arranged to form a virtual image of the image by reflecting a portion of the beam from the micro-optical structures. In the reflection, for at least a part of the beam reflected from the micro-optical structure, the resulting reflection deviates from the hypothetical reflection from the extrapolated substrate surface.
