The invention relates to a domestic appliance having a touch-sensitive operator control and display device (1, 1') which has a display unit (11, 11') for displaying operator control information and has a transparent support part (3, 16) on which a capacitive sensor electrode (13, 13') is arranged as part of a touch capacitor (18) which is arranged so as to overlap with the display unit (11, 11') and so as to overlap with a touch-sensitive operating area (10, 10') of the operator control and display device (1, 1'), wherein the sensor electrode (13, 13') is formed from a transparent and electrically conductive coating and/or adhesive which contains carbon nanotubes. According to a second aspect of the invention, the sensor electrode (13, 13') extends over an at least predominant region of extent of the display unit (11, 11'), wherein the operator control and display device (1, 1') has voltage-limiting means for applying an electrical voltage (V) to the sensor electrode (13, 13'), tapping means for tapping off a respective electric current from at least two tapping points (20 to 23) of the sensor electrode (13, 13'), and also has an evaluation device (24) which, in dependence on the tapped-off currents, determines a contact point at which an operator touches the operating area (10, 10'). |
