Abstract

PURPOSE:To reduce size and thickness of compound watch, by arranging terminals of common electrodes and a segment electrode, which are respectively divided into plural sections, on the bottom surface of an annular sealing layers on inside and outside. CONSTITUTION:Liquid crystal of annular sealing layers 23A and 23B on outside and inside are divided into plural sections and indicated and driven through first and second common electrodes 22A and 22B and a segment electrode of multiplex drive. A terminal 22BL of this electrode 22B is arranged in the sealing layer 23B, and a terminal of the electrode 22A is also arranged in the sealing layer 23B, Like- wise, a terminal of the segment electrode is arrnged in the sealing layer 23A, and therefore, structure of an annular liquid crystal indication cell for compound watch is to become a small and thin type.
