Abstract
In a display driving device which performs scan driving of a PDP or similar, to enable rapid scan operation, reduction of the chip size, and lowering of costs, as well as elimination of coupling problems. The display driving device is provided with a pull-up switching element Nu connected to a first driving voltage (VDH) supply line and common to all bits; diodes D1 to DN for each bit, connected between the pull-up switching element Nu and driving voltage output terminals for each bit; pull-down switching elements Nd1 to NdN for each bit, connected between a second driving voltage (GND) supply line and the driving voltage output terminals for each bit; and resistance elements R1 to RN for each bit, connected between the first driving voltage supply line and the pull-down switching elements Nd1 to NdN.
