摘要： A backlight module includes a backplane including a base plate, and a light guide plate disposed at a side of the base plate. A mounting hole is formed in the base plate, and a light source is installed in the mounting hole. The light guide plate includes a light guide portion located within a frame area of the backlight module, and a light emitting portion located within a transparent area of the backlight module. An orthographic projection of the light guide portion on the base plate at least covers the mounting hole, and the light guide portion is configured to reflect the light emitted by the light source to the light emitting portion.

摘要： The present disclosure relates to the field of display technology, particularly, discloses a backlight assembly and a display device. The backlight assembly includes a light guide plate and a light source. The light guide plate has a first light exiting surface and a second light exiting surface opposite to each other, and a light incident side intersecting with the first light exiting surface and the second light exiting surface. The light source is located at the light incident side of the light guide plate. The light guide plate has a refractive index which decreases first and then increases in a vertical direction from the first light exiting surface to the second light exiting surface.
