Abstract

PURPOSE: To obtain the illumination structure of the liquid crystal display unit which performs efficiently irradiation within the range of limited power source energy, by arranging a cover in a lamp part to make the lamp light incident efficiently onto a conductor.
CONSTITUTION: Conductor 7 consituted by transparent materials is installed in the lower face side of liquid crystal cell 10 which is arranged in wrist watch case 18, and reflection plate 8 is installed in the lower face side of conductor 7. The light source such as lamp 9 is provided on the side face of conductor 7. Cover 15 obtained by subjecting a metallic plate to plating is extended and arranged around lamp 9 so that cover 15 may join with conductor 7, so that the light radiated from lamp 9 can be incident onto conductor 7 without losing the light from the gap between cover 15 and conductor 7.
