Abstract

PURPOSE: To keep the illumination balance over the whole area of a display part by furnishing a dimming hole in a reflex layer-providing part around the display part farther than light source of a diffusion plate, allowing the reflex layer in the dinning hole to reflect light directly to a reflecting board, and concentrating the light on the display part farther than the light source. CONSTITUTION: When a dial 1 is illuminated at night, the light of an illumination bulb 6 passes that area of a diffusion plate 4 which is not covered with a reflex layer 5 and penetrates the display parts 3, 3' to illuminate them. In the display part 3' farther than the bulb 6, the light incident on a dimming hole 7 is reflected by the reflex layer 5 and proceeds to a reflecting board 8, and the light reflected thereby passes the diffusion plate 4 in the part of the display 3' and penetrates the display part 3'. In the display part 3' remote from the bulb 6, consequently, the light of the bulb 6 increases the brightness with repetitive reflections of the reflex layer 5 and reflecting board 8 so that a high brightness illumination is obtained. This generates a good illumination balance, and unevenness in the illumination can be eliminated.
