  • Patent number: 9458048
    Abstract: A glass cutter is provided which can form, using a wheel, a uniform crack in glass even when a projection or an earlier-formed scribe line is present on the glass. When the wheel is moved on the glass, a fracture layer is formed causing a rib mark to be formed below the fracture layer and a crack to be formed below the rib mark. To cut the glass, the crack is required to be formed uniformly. Applying a force to resist the rotating force of the wheel makes it possible to form a uniform crack even when a projection is present on the glass. This improves glass cutting yield.

  • Patent number: 8866993
    Abstract: In a liquid crystal display device having a display region defined by an area where a TFT substrate and an opposing substrate are superposed on each other, the present invention realizes a structure for avoiding breakage of a mechanically weak terminal section where the TFT substrate only extends. The terminal section where the TFT substrate only extends is mounted on a resin mold. Inside the resin mold, partition walls are formed to accommodate LEDs. By providing two partition walls in a pair at least in a center portion, an external pressure exerted on the center portion of the resin mold is distributed between the two partition walls and a maximum stress exerted on the terminal section of the TFT substrate is reduced.
