Abstract: A backlight assembly includes a light source, a light-guiding plate and a diffusion sheet that includes a first bead layer on a lower surface of the diffusion sheet facing the light-guiding plate, and a second bead layer on an upper surface of the diffusion sheet. To improve image display quality, the hardness of the beads of the first bead layer facing the light guide plate are equal to or less than that of the light guide plate to prevent scratching of the light guide plate.

Abstract: A flexible light guiding film includes a base film having a substantially constant thickness, and a light controlling portion disposed on the base film. Edges of the light controlling portion and the base film are coplanar and define a light incident surface of the light guiding film. The light incident surface is thicker than the base film, but has a similar thickness with that of a light exiting surface of a light source.

Abstract: A backlight assembly for an LCD device having a light guide plate that includes at least two thin layers and a plurality of optical sheets sequentially stacked over the rear surface of the liquid crystal panel.

Abstract: A display device is provided. The display device comprises a display panel. The display device further comprises a transparent film disposed on the display panel and a buffer layer having an adhesive characteristic interposed between the transparent film and the second plate.

Abstract: In a two-way backlight assembly and a two-way LCD apparatus, the two-way backlight assembly provides light emitted from one light source to a first direction where a main LCD panel is placed and to a second direction where a sub LCD panel is placed. Also, a sub mold part for receiving the sub LCD panel comprises a black-colored material so as to prevent reflection of the light. Accordingly, thickness and power consumption of the backlight assembly may be reduced and display quality may be also improved by preventing leakage of the light at ends of the sub LCD panel.

Abstract: A diffusively reflective film includes a base film, a light reflection layer and a light diffusion layer. The base film is flexible. The light reflection layer is disposed on the base film. The light reflection film reflects a first light. The light diffusion layer is disposed on the light reflection layer. The light diffusion layer diffuses the first light to form a second light. The diffusively reflective film may be bent to cover the light guide plate without being broken so as to increase the amount of light. Thus, a display quality is enhanced. Further, the diffusively reflective film covers the first side face, the second side face and the first face of light guide plate at once. Thus, productivity is enhanced and its manufacturing cost is reduced.

Abstract: A point light source includes a body, a light-emitting unit and a fluorescent unit. The body includes a bottom portion and a protrusion portion protruded from the bottom portion. The light-emitting unit includes a light-emitting chip disposed at the protrusion to have an inclined-angle with respect to the bottom portion. The fluorescent unit covers the bottom portion, the protrusion portion and the light-emitting chip. The point light source has an emitting-angle of about 180 degrees and luminance difference between a bright-portion and a dark-portion is decreased to enhance display quality of a display device.
