a backplane;
a light guide plate; and
a light source,
wherein:
the backplane comprises a first surface and a second surface opposite to the first surface;
the light guide plate comprises a light output portion provided on the first surface and a bending portion provided with a light input end on the second surface, and an end of the light output portion facing the second surface of the backplane is bent and extended to form the bending portion;
the light source is provided on the second surface and corresponds to a light input end face of the light input end;
a thickness of the bending portion is less than a thickness of the light output portion;
an end face of the backplane facing the bending portion is a curved surface;
the end face of the backplane facing the bending portion is coated with a protective layer; and
the thickness of the bending portion is gradually decreased along a direction from an end close to the light output portion to the light input end face, and the protective layer is an anti-scratch film layer.
