Abstract: A backlight assembly includes a receiving container, a plurality of lamps, and a diffusion plate. The lamps are received in the receiving container and are arranged substantially in parallel with each other to generate light. The diffusion plate on the lamps includes a plurality of light diffusing parts each having a plurality of embossed patterns corresponding to the lamps. Each of the embossed patterns has a circular shape or a polygonal shape in plan view and a substantially triangular cross-section or a semi-circular cross-section. Each of the embossed patterns is recessed or protruded from a surface of the diffusion plate to form a concave or convex shape, respectively. Therefore, a bright line of the backlight assembly is decreased to improve an image display quality of a display device.

Abstract: A backlight assembly is provided. The backlight assembly includes at least one lamp that generates a first light and a light diffusion member that is disposed over the lamp and diffuses the first light to generate a second light having a uniform brightness distribution. The light diffusion member includes a diffusion layer that diffuses the first light and a light path modulation member protruded from the diffusion layer to modulate a path of the first light. The light path modulation member is integrally formed with the diffusion layer.

Abstract: 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.

Abstract: A back light assembly comprises a light source, a power supply line, a receiving container, a fixing member and at least one connecting member. The light source generates light, and the power supply line supplies electrical power to the light source. The receiving container receives the light source. The fixing member is disposed on a rear face of the receiving container so as to attach the power supply line to the receiving container. The connecting member is disposed on the receiving container so as to couple the fixing member to the rear face of the receiving container. The power supply line may be firmly fixed to the receiving container so that a failure or a breakage of the power supply line may be prevented.

Abstract: A flat panel display device including a protecting sheet for protecting an upper surface is disclosed. The flat panel display device includes an image display part for displaying an image and a protecting part for protecting an outer surface thereof. The image display part displays the image by varying a voltage applied to electrodes oppositely formed on inner surfaces of a pair of transparent facing substrate respectively to thereby turn on or off each pixel. The protecting part is disposed on an outer surface of the substrate perceived by user's eye from an external shock or foreign mailers. Accordingly, the flat panel display device strongly resist the external shock, and the foreign matters are easily remove from the flat panel display device. The anti-glare treatment is carried out on the protecting sheet to thereby prevent dazzling of users due to the reflection of the light.

Abstract: An optical member is disposed between a light generating section that generates light and a display section that displays images by using the light generated by the light generating section. The optical member includes a light polarizing part and a light diffusing part. The light polarizing part polarizes the light generated by the light generating section. The light diffusing part is integrally formed with the light polarizing part to diffuse the light to enhance uniformity of luminance of the light. Therefore, weight, volume, etc. of the optical member may be reduced.

Abstract: 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.

Abstract: 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.

Abstract: A backlight assembly and a direct illumination type LCD apparatus having the same are provided. The backlight assembly has a light diffusion member including a diffusion layer for diffusing a first light emitted from at least one lamp and a light path modulation layer protruded from the diffusion layer to modulate the path of the first light, so the light diffusion member emits a second light having a uniform brightness distribution in response to the first light. The light path modulation layer may be disposed on one surface of the diffusion layer where the first light is inputted or another surface of the diffusion layer where the second light is emitted.
