Abstract

A translucent or transparent panel member which has a protrusion on the upper surface thereof is disposed on the upper surface of a plate-like luminescent member, to form a luminescent device. The luminescent device is manufactured by forming a protrusion on the upper surface of the panel member, providing a masking layer on the peripheral side surface and the upper surface, of the protrusion, forming a printed layer on the upper surface of the panel member, forming a printed layer on the upper surface of the protrusion after removing the masking layer from the protrusions, and arranging the panel member on the upper surface of the plate-like luminescent member. Such a plate-like luminescent device is arranged in the timepiece case to illuminate the analog hand mechanism. Such a plate-like luminescent device is also arranged in an electronic apparatus case to illuminate a liquid crystal display device of the electronic apparatus.
