Abstract: A level shift circuit which comprises a voltage applying part configured to apply predetermined voltage to a first node intermittently. An input part receives an input signal and applies reference voltage to a second node when a signal level of the input signal is equal to a first voltage level. A switching part connects the second node and the first node with each other during the voltage applying part does not apply the predetermined voltage to the first node. The switching part cuts off the connection between the second node and the first node during the voltage applying part applies the predetermined voltage to the first node. An inverter provides a phase-inverted signal of the signal given to the first node as an output signal.

Abstract: An operating device includes a display, a detector and a determiner. When the detector detects a designated position, the determiner determines whether or not a position corresponding to the designated position in a first layer is within a display region by first image data. When the position is within the display region, the determiner determines that the display region by the first image data is chosen. When the position is not in the display region, the determiner determines whether or not a position corresponding to the designated position in a second layer is within a display region by second image data. When the position in the second layer is within the display region by the second image data, the determiner determines that the display region by the second image data is chosen.
