Abstract: A display unit for a motor vehicle, having a display area with a back-lit liquid crystal display device bounded by a border area is provided. The display unit includes a light source, and behind the display area a liquid crystal cell, a first polarizer and a second polarizer, the light source being configured to provide back-light illumination to the cell and the polarizers forming a pair of polarizers on opposite sides of the cell such that, in use, the first polarizer polarizes the illumination and the second polarizer either passes or blocks this illumination when the polarization of the illumination is rotated by the cell. A first cover sheet extends over said cell, and a second cover sheet extends over the first cover sheet.

Abstract: A display unit for a motor vehicle, having a display area with a back-lit liquid crystal display device bounded by a border area is provided. The display unit includes a light source, and behind the display area a liquid crystal cell, a first polarizer and a second polarizer, the light source being configured to provide back-light illumination to the cell and the polarizers forming a pair of polarizers on opposite sides of the cell such that, in use, the first polarizer polarizes the illumination and the second polarizer either passes or blocks this illumination when the polarisation of the illumination is rotated by the cell. A first cover sheet extends over said cell, and a second cover sheet extends over the first cover sheet. One of these first and second cover sheets comprises a third polarizer and the other of these cover sheets comprises a neutral density filter, the third polarizer being aligned with the second polarizer such that the illumination passed by the second polarizer is passed by the third polarizer, and the first cover sheet is separated from the display area of the LCD device by a gap, such that ambient external light incident on the LCD device and reflected or scattered back towards the viewer from the display area is attenuated by two passes through the neutral density filter, and by two passes through the third polarizer.
