摘要： In a bottom-gate-type thin film transistor used in a liquid crystal display device in which a poly-Si layer and an a-Si layer are stacked, a quantity of an ON current which flows in the thin film transistor can be increased. A poly-Si layer and an a-Si layer are stacked on a gate electrode as an active layer by way of a gate insulation film therebetween in order of the poly-Si layer and the a-Si layer. An n+Si layer and a source/drain layer are formed on the a-Si layer thus forming a thin film transistor. A forward current which flows in the thin film transistor mainly flows in the poly-Si layer. To decrease contact resistance against the forward current between the poly-Si layer and the n+Si layer, an edge portion of the a-Si layer and an edge portion of the poly-Si layer assume a concavo-convex shape thus particularly increasing a contact area between the poly-Si layer and the n+Si layer whereby the contact resistance against the forward current can be decreased leading to the increase of a quantity of an ON current.
摘要翻译：在层叠多晶硅层和a-Si层的液晶显示装置中使用的底栅型薄膜晶体管中，可以增加流入薄膜晶体管的导通电流量。按照多晶硅层和a-Si层的顺序，通过栅绝缘膜将多晶Si层和a-Si层层叠在作为有源层的栅电极上。在a-Si层上形成n + Si层和源/漏层，从而形成薄膜晶体管。在薄膜晶体管中流动的正向电流主要在多晶硅层中流动。为了降低与多晶硅层和n + Si层之间的正向电流的接触电阻，a-Si层的边缘部分和多晶硅层的边缘部分呈现凹凸形状，因此特别增加了多晶硅层和n + Si层之间的接触面积，由此可以减小与正向电流的接触电阻，导致导通电流的增加。

摘要： The present invention provides a display device which forms a drive circuit using a bottom-gate-type TFT made of poly-Si which generates a small leak current in a periphery of a display region. A gate electrode is made of Mo having a high melting point, and a gate insulation film is formed on the gate electrode. A channel layer constituted of a poly-Si layer is formed on the gate insulation film, and the poly-Si layer is covered with an a-Si layer. An n+ Si layer is formed on the a-Si layer, and an SD electrode is formed on the n+ Si layer. Although holes are induced in the poly-Si layer when a negative voltage (inverse bias) is applied to the gate electrode, the holes cannot pass through the a-Si layer and hence, no drain current flows. Accordingly, it is possible to realize a bottom-gate-type TFT using poly-silicon which generates a small leak current.

摘要： In order to prevent dielectric breakdown of TFT or an interlayer insulating film by static electricity with a reduced area at low cost, a liquid crystal display device has a configuration in which an interlayer insulating film and an a-Si film are formed in a display area and a control area inside terminals. Image signal lines and scan lines are insulated from each other through the interlayer insulating film and a-Si film in their intersections. On the other hand, only the interlayer insulating film is formed between static electricity protection lines and an earth line outside the terminals. When static electricity is induced, dielectric breakdown is caused to occur in the area outside the terminals. Thus, the display area and the control area are protected from the static electricity.

摘要： A liquid crystal display device includes a semiconductor layer which is formed of a poly-Si layer and an a-Si layer and formed above a gate electrode with a gate insulating film interposed therebetween. A source electrode or a drain electrode is formed above the semiconductor layer. An n+Si layer is formed between the source electrode or the drain electrode and the semiconductor layer. Since ends of the source electrode or the drain electrode are formed inside ends of the semiconductor layer, leak current at the ends of the semiconductor layer can be reduced.
