A cooktop with a graphical display device is provided. The cooktop includes a glass ceramic substrate with a dead-front effect in which lightness differences in the display area and in particular differences between the latter and the adjacent areas of the cooktop are not visible for a user from the exterior. The cooktop has a glass or glass ceramic substrate and a display device with a display surface for displaying information by emission of light, wherein the display device is in the interior of the cooktop or cooking appliance such that light emitted from the display surface passes through the glass or glass ceramic substrate and is perceptible by a user in the exterior.
