  • Publication number: 20050231673
    Abstract: To simplify a manufacturing process of a transverse electric field mode liquid crystal display device by using a non-linear resistance element such as a TFD (Thin Film Diode) as a switching element. In a liquid crystal display device having a pair of substrates with liquid crystal interposed therebetween, one of the substrates consists of an electrode substrate. On the electrode substrate, there are provided a first group of electrodes, a second group of electrodes crossing the first group of electrodes with an insulating layer interposed therebetween, non-linear resistance elements, one end of each of the non-linear resistance elements being connected to the respective one of the second group of electrodes, and pixel electrodes opposing the first group of electrodes, each pixel electrode being connected to the other end of each of the non-linear resistance elements.

  • Patent number: 6332539
    Abstract: The present invention is a part retainer for housing and retaining various electronic and mechanical parts wherein a retaining unit has an engaging piece that stably stops at both a position at which it protrudes toward the opening of a part housing space and a position at which it withdraws, and which can move between these two positions under a specified or more amount of force, and wherein when protruding toward the opening, the engaging piece prevents the part housed in the housing space from falling out.
