Metrology and automation field device

A field device of measurement- and automation technology, comprising:

• a measuring transducer 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 adapted to display measuring- and/or operating parameters;
• and
• an electronic measuring/operating circuit 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,
• wherein the field device includes a housing having a housing wall and a housing chamber formed by the housing wall, in which housing at least the measuring/operating circuit is arranged,
• wherein the display unit has a screen having a first region with a first display technology and having a second region with a second display technology, and
• wherein the first region is embodied reflectively or transreflectively and the second region is embodied transmissively.
