Disclosed is a two-way display-type liquid crystal display device. The device includes a pair of upper and lower display modules for displaying different information; a plurality of two-way light sources for simultaneously supplying predetermined amounts of light rays to the upper and lower display modules; a light guide panel separately located at a side of the two-way light sources in a manner such that the upper and lower display modules are positioned on upper and lower surfaces of the light guide panel, respectively, the light guide panel functioning to guide light rays radiated from the two-way light sources in two directions toward the upper and lower display modules; a scattering film interposed between the light guide panel and the lower display module, for scattering and reflecting the light rays radiated from the two-way light sources, toward the upper display module; and a reflective and transmissive sheet interposed between the light guide panel and the lower display module, for reflecting one part of the light rays radiated from the two-way light sources, toward the upper display module, and transmitting the other part of the light rays toward the lower display module.
摘要:
A cosmetic composition according to the present invention may prevent the precipitation of caffeine at a low temperature, and thus may comprise a high concentration of caffeine that is effective in promoting lipolysis. Caffeine is known to promote lipolysis when applied to a human body. The cosmetic composition of the present invention may comprise a high concentration of caffeine, and thus can be valuably use in cosmetics or the like that requires effects of caffeine such as slimming effects, effect of relief from facial swelling or the like.
