An example device includes a light source, a liquid crystal layer, and an array of pixel electrodes disposed between the light source and the liquid crystal layer. The array of pixel electrodes is to control orientation of liquid crystal of the liquid crystal layer to modulate light incident from the light source to produce an image composed of pixels. The example device further includes an array of scattering electrodes to selectively influence orientation of liquid crystal of the liquid crystal layer to degrade contrast of selected pixels of the image.
