  • Patent number: 5614729
    Abstract: A transparent insulation film is formed on a glass substrate. Source and drain electrodes are formed on the transparent insulation film with their ends in spaced and opposing relation. The entire face of the substrate is treated with PH.sub.3 plasma to diffuse P atoms to form a doped surface layer. An a-Si semiconductor layer is formed on the doped surface layer so as to span a space between the source and drain electrodes with the opposite end portions of the semiconductor layer overlying those electrodes. A gate insulation film is formed on the semiconductor layer to extend all over the substrate. A gate electrode is formed of metal on the top of the gate insulation film 6 such that the opposite side edges of the gate electrode are recessed inwardly of the edges of the source and drain electrodes. An excimer laser beam is radiated against the face of the substrate with the gate electrode acting as a mask so that the laser-irradiated regions of the semiconductor layer comprise source and drain regions of n.

  • Patent number: 5576863
    Abstract: Liquid crystal is encapsulated between two transparent substrates 16, 17. Pixel electrodes 13 are formed on the inner surface of the transparent substrate 17 in the form of a matrix while a common electrode 12 is formed on the inner surface of the transparent substrate 16. Each pixel electrode 13 is divided into subpixel electrodes 13.sub.1, 13.sub.2. The subpixel electrode 13.sub.1 is connected to the drain of a thin film transistor 21 formed adjacent the subpixel electrode to apply driving voltage to the electrode. The subpixel electrode 13.sub.2 is supplied with capacitance-divided driving voltage through a capacitor comprising the electrode 13.sub.1, and a control capacitor 15 connected thereto with an insulation layer 14 interposed therebetween. Each of the subpixel electrodes 13.sub.1, 13.sub.2 are divided into two domains on which are formed alignment layers 41a, 41b, 42a, 42b, in opposition to alignment layers 43a, 43b, 44a, 44b formed on the common electrode 12.
