A liquid crystal display panel for displaying information of plural digits comprises transparent segment electrodes, reflection electrodes and a liquid crystal composition sandwiched therebetween. In a preferred form employing the typical seven-segment font, the transparent segment electrodes in the respective digit positions are divided into two groups. The reflection electrodes are continuously provided in common to the respective digit positions in such a manner that the reflection electrodes are provided even at the spaces positioned between adjacent digit positions and divided into four electrodes with the use of thin gaps provided longitudinally of the liquids crystal display panel. Both the respective two groups of the transparent electrodes and the respective four reflection electrodes are connected to receive selection signals for display.

Liquid crystal display

A heat sensitive type adhesive connector for providing electrical connection between terminals disposed on bases including a sheet made of heat sensitive type adhesive material for adhering said bases together, and electrically conductive and elastic particles mixed in the sheet, for providing electrical connection between the terminals.

In an electronic calculator essentially comprising a multidigit display, a keyboard and a data processor unit, a multidigit liquid crystal display is deposited together with integral key actuators of the keyboard on a flexible circuit film which carries electrical conductor leaves in a desired pattern. The conductor leaves to be in contact with terminals of the liquid crystal display are formed to extend in the direction of length of the liquid crystal display to thereby establish room for a battery compartment.
