Abstract

PURPOSE: To provide a timepiece whose hue varies with time, by driving three- primary-color polarization plates through an hour hand, a minute hand and a second hand.
CONSTITUTION: Light emitted from a cold-cathode tube 1, which is a light source, is diffused by an opalescent color diffusion disc 2 and then passed through a timepiece mechanism comprising a blue liquid crystal polarization disc 3, a transparent time disc 5 having a green liquid crystal polarization hour hand 6, a transparent minute disc 7 having a red liquid crystal polarization minute hand 8 and a red liquid crystal polarization second disc 9 having a green liquid crystal polarization second hand 10 and through a second polarization disc 11 bonded on a transparent disc 12, which serves as a color light detector, and an isotropic glass disc 13. This results in providing the timepiece whose hue varies with time.
