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.

A light guide plate includes a first surface having a light incident surface and a light reflect surface, a second surface facing the first surface, through which the reflected light exits, a first edge surface connected between edges of the light reflect surface and the second surface, and a second edge surface connected between edges of the light incident surface and the second surface, being opposite to the first edge surface. A light source is disposed on the light incident surface. A light guide plate may also include a stepped edge portion formed at a marginal area of the light guide plate on which a light source is combined. The stepped edge portion includes a light incident surface, a light reflect surface, an upper surface through which the reflected light exits the light guide plate, and a first edge surface connected between edges of the light reflect surface and the upper surface, being opposite to the stepped edge portion. A backlight assembly includes the light guide plate, a lamp unit including lamps and a lamp reflector that are disposed on the light incident surface, and a mold frame for receiving the stepped edge portion and the lamp unit.

In a backlight assembly capable of increasing luminance and preventing the breakage of an L CD panel and an LCD apparatus having the backlight assembly, the backlight assembly includes a light generating part, a light controlling part and a light condensing part. The light generating part generates a light. The light controlling part controls the light generated from the light generating part. The light condensing part is integrally formed with the light controlling part so as to condense the controlled light. Therefore, the light condensing part is integrally formed with the light controlling part so as to increase luminance and to prevent the breakage of the LCD panel and the warping of the reflective polarizing film.

Disclosed is an LCD device including an electromagnetic wave shielding member for shielding the electromagnetic waves generated from electric power applied to lamp of backlight assembly. The shielding member comprising conductive material is coated on surface of a diffusing plate to have mesh shape. The shielding member is filled into groove formed on the surface of the diffusing plate to have mesh shape. Accordingly, the electromagnetic waves may be shielded from the LCD panel. Furthermore, the shielding member makes electrical contact with the chassis of the LCD device through various ground members so as to be connected to an earth potential, thereby being stabilized electrically. Accordingly, display quality of the LCD device is improved. A conductive tape is used as the ground member, and the conductive tape is strongly fixed to the chassis of the LCD device by means of conductive fixing clip or conductive screw.

In a backlight assembly and a liquid crystal display device using the backlight assembly, a lamp assembly is mounted on a receiving container and includes lamps. The lamps are connected in parallel and are turned on by the power voltage supplied from a lamp driving module. Sensors are disposed in the receiving container to face the lamps, and detect operation state of the lamps to output sensing signals. A voltage cut-off module is disposed outside of the receiving container, provides the lamp driving module with a voltage cut-off signal when at least one of the sensing signals has an amplitude smaller than a reference signal. The deterioration of the lamps may be prevented, and the life expectancy of lamps may be increased.

Disclosed is an LCD device including a noise shielding member. The noise shielding member is a transparent conductive member including a transparent film on which a transparent conductive layer is coated. The noise shielding member may also be a transparent conductive layer scattered on the optical sheets. The transparent conductive layer comprises ITO or IZO. The noise shielding member is disposed under the diffusing plate or interposed between optical sheets. The noise shielding member may be disposed under the LCD panel. The noise generated from the electric power signal applied to the lamp of the backlight assembly is shielded from the LCD panel. Furthermore, the noise shielding member and optical sheets contacts with the chassis of the LCD device through various ground members so as to be connected to earth potential and be electrically stabilized. Accordingly, display quality of the LCD device is improved.
