Abstract

PURPOSE: To increase the function without increasing the power consumption, by color display of the time system information normally displayed with EC cell, and by the display of liquid crystal for many functions such as second display short in period and full calendar having many patterns.
CONSTITUTION: In the electro-optic display unit 1, the EC cells 3aW3e are located under the crystal cell 2a. EC cells perform color display for the month 3c, day 3d, weekday 3e, hour 3a, minute 3b, and coron mark 3f, and only the second display short in the selection period is displayed with the liquid crystal cell 2a. Further, EC cells are made no display and the dispaly plane is used as the reflection surface of the liquid crystal cell, and the full calendar or stop watch display can be also made to the liquid crystal cell.
