A liquid crystal display element-driving circuit wherein output signals from a decoder for decoding coded time data are supplied to a plurality of exclusive OR gates through the corresponding NAND gates; an output signal from a liquid crystal driving pulse generator is sent forth in common to the exclusive OR gates, and outputs from the respective exclusive OR gates are conducted to the corresponding segment electrodes of the liquid crystal display element, and which further comprises first and second logical level voltage-generating circuits; switch circuits controlled by said first and second logical level voltage-generating circuits, whereby all the segment electrodes can be impressed with voltage having the same logical level by means of said first and second logical level voltage-generating circuits and corresponding switch circuits.
A driving circuit for a liquid crystal display device for causing the segment electrodes of a liquid crystal element to indicate prescribed data, which comprises a plurality of multi-input type NAND gates supplied with outputs from a decoder circuit for decoding coded data;
