Abstract
A backlight module includes a light source unit for providing light, a light guide plate including a plate body having a light entrance surface and extending along an X-Y plane and at least one opening in the plate body and extending along a Z axis, and an optical layer on one side of the light guide plate. The light enters the light guide plate from the light entrance surface and travels substantially along the X-Y plane. A cross section of the opening on the X-Y plane is a taper shape with a base region and a cone shape region extending from one side of the base region near the light source unit. The optical layer has a through hole aligned and communicating with the base region. A projection of the cone shape region along the Z axis on the optical layer is at least partially outside the through hole.
