To prevent particles from infiltrating into a display apparatus, a liquid crystal display panel supporting member includes a first particle interceptor and a second interceptor. The first particle interceptor is formed along the top face of the first supporting member frame portion facing a bottom plate of a liquid crystal display panel that is to be mounted on the liquid crystal display panel supporting member. The first particle interceptor has at least two cut portions. The second particle interceptor is disposed between the cut portions to prevent particles from infiltrating into the first particle interceptor. Thus, the liquid crystal display apparatus may prevent deterioration of its display quality.

A light-guide plate includes an incident surface receiving light, an upper surface extended from a first side of the incident surface, a lower surface opposed to the upper surface and a plurality of first prisms protruding from the upper surface and spaced apart by a separation distance.

There is disclosed a backlight assembly for maximizing a light incidence efficiency by changing a construction of a light guide plate and a liquid crystal display device having the same. A light incidence surface of the light guide plate receiving a light from a lamp is inclined to make an obtuse angle with a light-emitting surface through which the light is transferred to the display unit. An open surface of a lamp cover that is disposed to face towards the light incidence surface is formed to have the same inclined angle as the light incidence surface of the light guide plate. In addition, a light reflecting plate and an optical sheet are respectively disposed on the top and bottom surfaces of the light guide plate, on which light absorbing layers, for absorbing light that leaks from the light guide plate, are formed at both ends thereof. Accordingly, there are advantages in that the light incidence efficiency of the light is improved even though a thickness of the light guide plate is not increased, and that it is possible to remove the light concentrated at an edge of the light incidence surface of the light guide plate.

A backlight assembly has a light diffusion member including a diffusion layer for diffusing first light emitted from at least one lamp and a light path modulation layer formed on the diffusion layer to modulate the path of the first light, Therefore, the light diffusion member emits second light having uniform distribution of the brightness. The light path modulation layer may be disposed on one surface of the diffusion layer where the first light is input, or another surface of the diffusion layer where the second light is emitted.
