Abstract
A CMOS-LSI including a time information keeping circuit and a display driver circuit is mounted on a flexible film substrate. An upper plastic housing and a bottom plastic housing are provided for tightly supporting the flexible film substrate through screws. That is, the flexible film substrate is sandwiched between the two plastic housings at the periphery thereof, thereby minimizing the flexibility of the flexible film substrate.
