摘要： A liquid crystal display device intended for increasing the ON-current of a TFT in the pixel while suppressing variation of the ON-current, in which a semiconductor layer and a first n+-a-Si layer in the TFT are formed continuously by plasma CVD. The semiconductor layer and the first n+-a-Si layer are patterned simultaneously. Then, a second n+-a-Si layer is formed so as to cover the upper surface of the first n+-a-Si layer and the side portion of the semiconductor layer. The ON-current can be increased and variation of the ON-current of the TFT can be decreased by forming the first n+-a-Si layer continuously over the semiconductor layer.

摘要： Gate electrodes are formed on a substrate. A gate insulation film is formed so as to cover the gate electrodes. A semiconductor layer is formed in regions on the gate insulation film in a region which overlap with at least the gate electrodes. Plasma treatment is applied to the semiconductor layer using a gas which contains a dopant thus increasing impurity concentration of a surface layer of the semiconductor layer. A conductive film is formed on the surface layer of the semiconductor layer to which the plasma treatment is applied. A source electrode and a drain electrode are formed by etching the conductive film.

摘要： In bottom-gate-type thin film transistors used in a liquid crystal display device, a channel stopper layer is formed on a poly-Si layer thus stabilizing a characteristic of the thin film transistor. The channel stopper layer is formed into a desired shape by wet etching, and the poly-Si layer is formed into a desired shape by dry etching. By applying side etching to the channel stopper layer, a peripheral portion of the poly-Si layer is exposed from the channel stopper layer, and this region is brought into contact with an n+Si layer. Due to such constitution, ON resistance of the thin film transistor can be decreased thus increasing an ON current which flows in the thin film transistor.

摘要： A pixel is formed by sealing an insulating liquid and floating particles in an area defined by a first substrate, a second substrate and partitions. The width of the partition has to be reduced in order to improve the pixel brightness by enlarging a flat electrode. In this case, the height of the partition has to be reduced for retaining the mechanical strength. If the height of the partition is reduced, an area of the partition electrode becomes small, thus failing to retain the memory effect. The planar surface of the partition is then formed into a zigzag shape so as to increase the area of the partition electrode.
摘要翻译：通过在由第一基板，第二基板和隔板限定的区域中密封绝缘液体和浮动颗粒来形成像素。必须减小分隔件的宽度，以便通过放大扁平电极来提高像素的亮度。在这种情况下，为了保持机械强度，必须减小隔板的高度。如果隔板的高度减小，则分隔电极的面积变小，因此不能保持记忆效果。然后将隔板的平面形成为锯齿形，以增加分隔电极的面积。
