The light guide plate comprises: a light incident surface formed with a plurality of first microstructures thereon, the plurality of first microstructures being configured to deflect a part of light entering through the light incident surface toward the light incident surface of the light guide plate; and at least one cavity inside the light guide plate, a side wall of each cavity distant from the light incident surface being formed with a plurality of second microstructures thereon, the plurality of second microstructures being configured to further deflect a part of the light striking on the second microstructures through the cavity toward the light incident surface of the light guide plate. The light guide plate of the present invention of the present invention is able to reduce an area of a dark strip zone occurring at a light incident portion of the light guide plate, thus alleviating the phenomenon of alternate bright and dark strip zones occurring at the light incident portion of the light guide plate, thereby improving display performance of the display apparatus.
