PURPOSE:To reduce spike noises by connecting capacitors between the connection point of the 1st and the 2nd resistance elements and the connection point of the 4th and the 5th resistance elements and across the 3rd resistance element. CONSTITUTION:The 1st - the 5th resistance elements 1-5 are connected in series between the 1st power source which has a source voltage VDD and the 2nd power source 1 which has a source voltage V0, and a common nonselection level voltage V2, a segment nonselection level voltage V3, a segment nonselection level voltage V4, and a common nonselection level voltage V5 are obtained by resistance division at connection points of the respective resistance elements. A capacitor 10 is connected between the connection point of the resistance elements 1 and 2 to which a voltage V2 is led out and the connection point of the resistance elements 4 and 5 to which a voltage V5 is led out, and a capacitor 11 is connected across the resistance element 4. Consequently, spike noises generated in the source voltages of the respective levels during data switching are reduced.
