         5 . The earth boring device ( 1 ) according to  claim 1 , wherein the display ( 9 ) enables a display on an area of at least 50 cm 2 . 
     
     
         6 . The earth boring device ( 1 ) according to  claim 1 , wherein the display ( 9 ) and the operating part ( 4 ) are designed such that the display ( 9 ) is arranged in a receptacle of the operating part ( 4 ). 
     
     
         7 . The earth boring device ( 1 ) according to  claim 1 , wherein, when the earth boring device ( 1 ) is switched on or started, a safety control, a monitoring device ( 8 ) and/or a controller are designed in such a way that the largest range and/or the largest opening angle of the sensors ( 6 ,  7 ) are adjusted. 
     
     
         8 . The earth boring device ( 1 ) according to  claim 1 , wherein a switch which can be actuated by an actuator is provided for switching the range and/or the opening angle, and the safety control, monitoring device ( 8 ) and/or a controller are designed such that a request for an acknowledgment is received and/or an automatic switch-over depending on the inclination of the carriage ( 16 ) of the earth boring device ( 1 ) is provided. 
     
     
         9 . The earth boring device ( 1 ) according to  claim 1 , wherein the at least one sensor ( 6 ,  7 ) is arranged on a support ( 5 ) of the earth boring device ( 1 ). 
     
     
         10 . The earth boring device ( 1 ) according to  claim 1 , wherein the safety control has a multi-channel, in particular two-channel, input which is designed to carry a signal of a response of the sensors ( 6 ,  7 ). 
     
     
         11 . The earth boring device ( 1 ) according to  claim 1 , wherein a safety control and/or a controller are designed to forward signals from the monitoring device ( 8 ) to the control device. 
     
     
         12 . A method for monitoring a region in an earth boring device ( 1 ) for introducing, in a rotating, pushing and/or pulling manner, a boring string ( 2 ) into the ground ( 3 ), wherein the boring string ( 2 ) extends in a region in which the boring string ( 2 ) exits the earth boring device ( 1 ) and enters the ground ( 3 ), and a presence or a movement, in particular of a person, is monitored in the region, wherein an operating part ( 4 ), in particular a remote control, is used to control functions of the earth boring device ( 1 ), wherein a monitoring device ( 8 ) is used for monitoring, which device has sensors ( 6 ,  7 ), and when a presence and/or a movement, in particular of a person, is detected, a signal is sent to a display ( 9 ), in order to trigger an adjustment of the display ( 9 ) on the display ( 9 ).
