Abstract

PURPOSE:To reduce the size of a watch by eliminating the need for a liquid- crystal support frame, by positioning a liquid-crystal cell, positioned temporarily by a photoconductive plate, by the press member of a device cover in assembling a watch module. CONSTITUTION:Before a watch module is assembled, a liquid-crystal cell 1 is positioned temporarily by a photoconductive plate 4 equipped with photoconductive rubber parts 7 and 8, projection parts 4c.... When the watch module is assembled, it is positioned finally by a liquid-crystal cell press member 11 incorporated in a device cover 9. Thus, the need for a liquid-crystal cell support frame, etc., for positioning is eliminated to reduce the size fo the watch module.
