摘要： A signal sampled by a sampling transistor is amplified with low power consumption. A display voltage signal Vsig sampled by the sampling transistor is amplified by an amplifier circuit of this invention. A thin film transistor T1 which functions as a MOS capacitance is connected to a signal line DL to which the display voltage signal Vsig is outputted. A voltage boosting pulse VP1 is applied to a gate of the thin film transistor T1. And the thin film transistor T1 is switched from ON to OFF during change in the rising pulse. The amplifier circuit amplifies the signal through the use of difference between the gate capacitance of the thin film transistor T1 in ON state and the gate capacitance of the thin film transistor T1 in OFF state.

摘要： The extending direction of a gate electrode configured by protruding a portion of a gate signal line is tilted with respect to the extending direction of the gate signal line. To form the active layer of a switching TFT, a focused laser is irradiated on an a-Si film to form a p-Si film. During this process, the long-axis direction of the laser is oriented either orthogonally or in parallel with respect to the extending direction of the gate signal line. Accordingly, by tilting the extending direction of the gate electrode with respect to the extending direction of the gate signal line, a junction portion between a channel and a source/drain is prevented from entirely overlapping a periphery portion of the laser along its long-axis direction. This arrangement prevents generation of leak current in the switching TFT, realizing a stable EL display device.
摘要翻译：通过使栅极信号线的一部分突出而构成的栅电极的延伸方向相对于栅极信号线的延伸方向倾斜。为了形成开关TFT的有源层，将聚焦的激光照射在a-Si膜上以形成p-Si膜。在该过程中，激光器的长轴方向相对于栅极信号线的延伸方向正交或平行取向。因此，通过使栅电极的延伸方向相对于栅极信号线的延伸方向倾斜，可以防止沟道与源极/漏极之间的接合部分沿着其长轴方向与激光器的周边部分完全重叠方向。这种布置防止在开关TFT中产生漏电流，实现稳定的EL显示装置。
