ABSTRACT:
An electronic table calculator is provided having a liquid crystal display and an integrated circuit element defining one or more of the display-driving circuitry or the calculating circuitry thereof. The liquid crystal display is defined by a pair of spaced plates having liquid crystal material therebetween contained by a spacer. At least one of the plates projects beyond the spacer and has formed on the same inner surface thereof, electrode portions within the spacer forming a part of the liquid crystal display and electrode portions outside of the spacer to which the integrated circuit element is coupled by face-down bonding.
