摘要： A timepiece for colorful multicolor display consuming a small amount of electric power, comprising an ordinary black-and-white liquid crystal drive IC and produced at low cost. The timepiece includes a liquid crystal display device (17) of double-refraction color type and a drive module (27) for driving the liquid crystal display device both being contained in a case (25) having a windshield glass. The display unit of the liquid crystal display device (17) is provided with an ordinary time display unit for a single-color display and a mark display unit for rendering colorful display in a plurality of colors. The drive module (27) includes a liquid crystal drive circuit for driving the liquid crystal display device (17) by applying scanning signals to the scanning electrodes of the time display unit and applying data signals to the scanning electrodes of the mark display unit.

摘要： To provide a colorful timepiece capable of displaying in multiple colors at a low power consumption and with a low development cost using a typical monochrome liquid crystal driving IC, a birefringence color liquid crystal display device (17) and a driving module (27) for driving the liquid crystal display device are installed inside a case (25) with a cover glass. A time display portion displaying normal time in a single color and a mark display portion displaying in a plurality of colors, are provided in a display portion of the liquid crystal display device (17). A liquid crystal driving circuit for driving the liquid crystal display device (17) to supply a scanning signal to scanning electrodes for the time display portion and a data signal to data electrodes for the mark display portion, is provided in the driving module (27).
