Method of manufacturing a display plate and display apparatus

In carving a decorative groove ( ) formed in V-shape cross section extending from inside to outside on a dial plate ( ) of a timepiece as a decorative plate, the slant angle of an inner slanted side ( A) forming the V-shape of the decorative groove ( ) is made gentler than an outer slanted side ( B) at an inner part of the spiral, so that action of light reflected on the flat surface of the dial plate ( ) macroscopically becomes similar to the light reflected on a bulging surface to give the central portion of the dial plate ( ) a bulging appearance, whereby a three-dimensional effect is provided by the decorative groove ( ) even when the dial plate ( ) is made of a thin plate, thereby adding depth and a luxurious touch or aspect.
