  • Patent number: 7046312
    Abstract: There is disclosed a small-sized, active matrix liquid crystal display having high reliability. The liquid crystal display comprises a TFT substrate, a counter substrate, and a layer of a liquid crystal material held between these two substrates. A plurality of pixel TFTs are arranged in rows and columns on the TFT substrate. Driver TFTs forming a driver circuit for driving the pixel TFTs are formed also on the TFT substrate. All of these TFTs are covered by the liquid crystal material directly or via a thin film to protect these TFTs. A short ring is cut after a rubbing operation and before bonding of the substrates. Therefore, during manufacturing, the TFTs are protected from static charges. Also, the cutting operation is facilitated.

  • Patent number: 6953714
    Abstract: A method for producing a thin film semiconductor device is described. In the method, a thin film layer of non-single-crystalline semiconductor, which is deposited on a base layer of glass, is processed to an island-shaped thin film layer at the time prior to the layer irradiation step. The laser irradiation to the thin film layer of non-single-crystalline semiconductor is carried out after forming an insulation film layer and a gate electrode over the island-shaped thin film layer, by using the gate electrode as the irradiation mask, whereby the center area of the island-shaped thin film layer masked by the gate electrode is crystallized, and simultaneously, the both side areas thereof which is not masked by the gate electrode are annealed. Next, a source electrode and a drain electrode is formed in the annealed areas. The implantation of impurity ion may be carried out either before or after the laser irradiation.
