Abstract

Arrangement for a display device which can be acted upon by light and is provided with a display surface, and which can be acted upon by light striking it substantially parallel to the said display surface. By means of the invention the light is distributed effectively over the whole of the display surface of the device. According to the invention a plate (1) or the like, made of plexiglass or a material with similar light-conducting properties, has a curved surface (3) on the opposite side to the said preferably planar display surface (2) of the said plate.
