Abstract

PURPOSE: To make display at a mechanical display part possible without deforming an electrical display part complicatedly, by arranging the electrical display part composed of a liquid-crystal element at the front side and the mechanical display part on its back surface.
CONSTITUTION: Glass-substrate upper board 3 fitted with clear electrode 4 and lower board 5 provided with clear electrode 6 as well are combined, liquid crystal 7 is sealed between the both, and polarization boards 8 are provided to both external surfaces, thereby constituting a liquid-crystal display element used as electrical display part 1. In contact with one surface of one polarization board 8 of the liquid- crystal element, mechanical display part 2 such as an odometer showing the running distance of a vehicle is arranged. In this constitution, when the driver of the vehicle does not need the display value of the odometer, switch 10 is OFF to make the liquid crystal unlighted. On the other hand, when the display value of the odometer is required, switch 10 is turned ON to light the liquid crystal via exclusive- OR circuit 13, thereby reading the display value of the odometer at the reverse side.
