A display panel includes an array of refractive elements arranged on a substrate. The array is positioned to receive light of a first intensity profile and configured to transmit in a second intensity profile at least some of the light received. The display panel also includes a diffuser positioned to receive the light transmitted by the array of refractive elements and configured to transmit in a third intensity profile at least some of the light received. The second intensity profile has a lower relative intensity normal to the substrate than has the first intensity profile.
