  • Patent number: 8587511
    Abstract: A liquid crystal display panel includes a first substrate, a second substrate and a liquid crystal layer. The first substrate includes a plurality of pixels and a plurality of sensing parts. Each of the sensing parts generates an output signal containing location information in response to an input signal. The location information indicates a location where the input signal is inputted. The second substrate is connected to the first substrate. The second substrate faces the first substrate. The liquid crystal layer is interposed between the first substrate and the second substrate. The liquid crystal display device needs no additional touch panel, so that no air space exists between the liquid crystal display panel and the touch panel. Therefore, a display quality is enhanced.

  • Patent number: 6689779
    Abstract: The present invention relates to novel oxazolidinone derivatives, their pharmaceutically acceptable salts and a process for the preparation thereof. More particularly, the present invention relates to oxazolidinone derivatives having pyridine or pyrimidine moeity substituted by heterocycle and heteroaromaticcycle at 4-position of phenyl ring. The compounds of the present invention have wide antibacterial spectrum, superior antibacterial activity and low toxicity, such that the compound of this invention can be used as an antibacterial agent.
