Abstract
The positioning device includes a backboard and a spring member arranged adjacent to the incident surface of the light guide plate, and includes a connector attached to the backboard, and a positioning hand having a fixing end and a free end. The fixing end is secured to the connector, and the free end abuts against to the sidewall of the light guide plate so as to correctly position the light guide plate with respect to the light source. The spring member absorbs expansion and contraction of the light guide plate.
