A display device includes having a display panel, a light source disposed on a rear surface of the display panel, and an optical member disposed between the display panel and the light source. An optical member supporter is configured to support at least one side of the optical member and includes at least one pair of a first hook and a second hook formed on a rear surface. The display device also includes a bottom chassis having a first inserting hole and a second inserting hole into which the first hook and the second hook are respectively inserted, a driving circuit substrate disposed between the bottom chassis and the second hook, and at least one flexible printed circuit board configured to connect the display panel and the driving circuit substrate.

A wire fixation apparatus and a display device are provided. The wire fixation apparatus includes: a first snap structure, half surrounding a wire and provided with a first opening at a side thereof; a second snap structure, half surrounding a wire and provided with a second opening at a side thereof; and an auxiliary installation plate connecting the first snap structure to the second snap structure. The first opening of the first snap structure is opposite to the second opening of the second snap structure. The first snap structure, the second snap structure and the auxiliary installation plate together form a wire channel for the wire to pass therethrough, and an interval is arranged between the first snap structure and the second snap structure to enable the wire to be snapped into the wire channel through the interval. Projections of the first snap structure, the second snap structure and the auxiliary installation plate onto a first projection plane together encircle a projection of the wire onto the first projection plane. The first projection plane is a plane of a cross section of the wire.
