Claims

1. A timepiece dial comprising: a base member made primarily of polycarbonate;a silicon compound layer made primarily of a silicon oxide compound; anda zinc sulfide compound layer made primarily of a zinc sulfide compound and rendered on the opposite side of the silicon compound layer as the side facing the base member.

2. The timepiece dial described in claim 1, wherein the silicon compound layer is primarily SiO2.

3. The timepiece dial described in claim 1, wherein the thickness of the silicon compound layer is 20 nm to 200 nm.

4. The timepiece dial described in claim 1, wherein the thickness of the zinc sulfide compound layer is 10 nm to 100 nm.

5. The timepiece dial described in claim 1, wherein the combined thickness of the silicon compound layer and the zinc sulfide compound layer is 50 nm to 250 nm.

6. The timepiece dial described in claim 1, further comprising a polarizer having the ability to polarize incident light disposed to the opposite side of the base member as the side on which the zinc sulfide compound layer is disposed.

7. The timepiece dial described in claim 6, further comprising a color layer composed of a material including a coloring agent between the base member and the polarizer.

8. The timepiece dial described in claim 7, wherein the color layer is made from a material that is sticky and adhesive.

9. The timepiece dial described in claim 6, further comprising a diffusion layer composed of a material containing a diffusion agent having the ability to disperse incident light, the diffusion layer being disposed between the base member and the polarizer.

10. The timepiece dial described in claim 9, wherein the diffusion layer is made from a material that is sticky and adhesive.

11. The timepiece dial described in claim 1, wherein the color of the surface on the side to which the zinc sulfide compound layer is disposed has an a* value of −10 to 10 and a b* value of −10 to 10 in the L*a*b* color space defined in JIS Z 8729.

12. A timepiece comprising the timepiece dial described in claim 1.
