WITH A DIAL FOR TIMEPIECE COMPRISING A DECORATION MEMBER (21) HAVING A PLURALITY OF THROUGH HOLES (22) FORMED VERTICALLY ON A LUMINESCENT MEMBER (10), THE CROSS-SECTIONAL AREA OF LOWER-SIDE HOLES (24) OF THE DECORATION MEMBER (21) IS FORMED TO BE LARGER THAN THAT OF UPPER-SIDE HOLES (23). THEREFORE, EVEN IF A SUBSTRATE IS THICK, THE DIAMETER OF THE UPPER-SIDE HOLES (23) OF THE THROUGH HOLES (22) CAN BE FORMED TO BE SMALL SUFFICIENTLY. MOREOVER, COMPARED TO A DIAL SIZE (20) FOR A TIMEPIECE WHEREIN THE DECORATION MEMBER (21) IS PLACED ON THE LUMINESCENT MEMBER (10), THE DIAMETER OF THE THROUGH HOLES (22) OF THE DECORATION MEMBER (2)1 IS SMALL. THUS, IT IS POSSIBLE TO TAKE IN ENOUGH LIGHT FROM THE LUMINESCENT MEMBER (10) THROUGH THE LOWER-SIDE HOLES (24) TO ENSURE THE SUFFICIENT AMOUNT OF THE LIGHT THROUGH THE THROUGH HOLES (22) . IT IS POSSIBLE TO LUMINESCENT OBTAIN SUFFICIENT ILLUMINANCE FOR THE DIAL. FIG 1 AND FIG 3D
