Abstract: The invention relates to a field device of measurement- and automation technology, comprising: a measuring transducer which is adapted to register at least one measured variable and, at any one time, to output at least a first measured value representing the measured variable; a display unit which is adapted to display measuring- and/or operating parameters; and an electronic measuring/operating circuit which is adapted to operate the measuring transducer and/or the display unit, as well as to calculate from the first measured value a derived, second measured value. The display unit has a screen that has a first region with a first display technology and a second region with a second display technology. The first region is embodied reflectively or transreflectively and the second region is embodied transmissively.
