A transreflector (1,2) for transmitting light emitted by a panel surface of a backlight (BL) incident on a first side of the transreflector (1,2) and for reflecting ambient light incident on a second side of the transreflector (1,2) opposite the first side. The transreflector (1,2) comprises reflective surfaces (9) for reflecting ambient light incident on the second side of the transreflector (1,2), and light transmissive surfaces (10) for transmitting light emitted by the panel surface and incident on the first side of the transreflector (1,2). The light transmissive surfaces (10) of the transreflector have an angular shape pattern that changes with the distance from the input edge of the panel member to compensate for changes in the angular distribution of the light emitted by the panel surface as the distance from a light input edge of the panel member increases.
