Abstract

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.
