Abstract
The invention provides according to one example a display device for a domestic electric heating appliance, such as for example a glass ceramic hob, the electric heating appliance having at least one heating device. The latter is subdivided into several flat heating areas, which can be activated at least partly independently of one another and/or singly for heating operation. The display device optically displays the heating operation or the activation of individual heating areas. For this purpose it has individually activatable illuminating devices. The illuminating devices are constructed as separate segments of a geometrical basic shape, such as a rectangle or preferably a circle. For each display device there are two basic shapes of the same nature, but different size and having a concentric arrangement.
