Abstract
A display device is configured such that a through-hole extends through a liquid crystal panel and a light guide plate, a fastener for coupling the hands of a watch is coupled to the through-hole, and the formation of a dark region is prevented due to interference between the fastener and light from a light source around the through-hole. At least one flat side surface for minimizing interference with the light from the light source is provided on the fastener, whereby uniform luminance is provided around the through-hole.
