ABSTRACT An electronic calculator comprises mainly a multi- digit liquid crystal display unit, a mechanical contact-type keyboard unit and a semiconductor circuit unit including a computation circuit, logical control circuit, storage circuit, program memory circuit, etc, these units all being provided on a single plate of electrically insulating material. The plate is one of a pair of spaced-apart electrically insulating plates forming a capacity for the liquid crystal composition, is of a length sufficient to support all the constitutional units, and has two major surfaces, one for supporting the keyboard unit and the other for supporting the semiconductor circuit unit. Connec- tion between the keyboard unit and semiconductor circuit unit is accomplished by any conventional method, for example, multi- terminal connectors, conductively material printing, through holes, wire bonding, etc.
