Abstract
A breathing apparatus with a display unit for the transmission of measured data via a display field of the display unit into the field of vision of a person wearing the unit. The readability of the measured data displayed is improved in daylight with simultaneously reduced energy demand. The display field includes an LC display, which is at least transparent for transmission radiation. An optical concentrator is provided, which collects the ambient light via a light entering surface and emits the collected light via a light exiting surface.
