PROBLEM TO BE SOLVED: To provide a decoder circuit that prevents the delay of decoder output. SOLUTION: A switch 16 that is put into an ON state when a node A 60 of an NMOS region 12 is not an output channel of a selected gradation voltage, is connected to the node A 60. Thus, electric charges are accumulated on the node A 60 by a coupling capacity C1 caused in the node A 60 when the selected gradation voltage is output from an output terminal of the decoder output DECOUT, and a raised voltage is discharged by the switch 16 in the ON state.
