摘要： In an LCD apparatus having an optical member, the optical member has a base body having a light incident surface and a light emitting surface faced the light incident surface. A first resin layer is formed on the light emitting surface and a light diffusing pattern is uniformly formed on the first resin layer so as to diffuse a first light and emit a second light. Accordingly, the LCD apparatus can improve display quality and can be fabricated in low-cost manufacture. Also, since the light diffusing pattern is formed with a curable material, the light diffusing pattern can have various shapes and superior reproducibility.

摘要： 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.

摘要： A backlight assembly includes a light guide plate including a light incident face, a light exiting face extended from one end portion of the light incident face, and a reflection face extended from another end portion of the light incident face. The reflection face includes a first reflection face extended from another end portion of the light incident face, and a second reflection face horizontally extended from the first reflection face. The backlight assembly additionally includes a light adsorption member disposed adjacent to the reflection face to prevent the light from reflecting. A reflection plate and optical sheets are disposed adjacent to the light guide plate, so that entire thickness of the backlight assembly is reduced. In addition, leakage of the light incident around the third light exiting face is prevented to improve the quality of the image displayed through the LCD device.

摘要： A light guide plate includes a light incident surface for receiving light, first and second light emission surfaces for emitting light at a first light emission angle with respect to the first and second light emission surfaces, and a light reflection pattern formed on the first light emission surface, for reflecting the light toward the second light emission surface. The reflected light from the light reflection pattern exits the second light emission surface at a second light emission angle with respect to the second light emission surface, and the second light emission angle is larger than the first light emission angle. The light reflection pattern includes multiple dots each having a prim pattern on their surface and light reflecting surfaces elongated in a selected direction. The adjacent light reflecting surfaces meet each other at their elongated edges to form a prism shape.
