摘要:
An active matrix substrate includes a transistor, a pixel electrode connected with one of the current-flowing electrodes of the transistor, a storage capacitor wiring, a lead wiring extending from one of the current-flowing electrodes of the transistor, and a repair wiring extending from the storage capacitor wiring. The repair wiring overlaps a portion of the lead wiring with an insulating layer interposed therebetween. As a result, TFT defects (for example, a short circuit between a source electrode and a drain electrode) can be repaired, and performance of fast display and reduction in electric power consumption can be realized.

摘要:
An active matrix substrate includes a transistor, a pixel electrode, a drain lead electrode connected with the drain electrode of the transistor, and a contact hole connecting the drain lead electrode and the pixel electrode. A non-electrode through-bore portion is created on the drain lead electrode, and an opening of the contact hole crosses the through-bore portion. As a result, any changes or decreases in the contact area between the drain lead electrode and the pixel electrode may be prevented or reduced significantly, while the open area ratio can be improved.

In a liquid crystal display, a first data signal line and a second data signal line are provided for each pixel column. In at least one embodiment, in a case where every two pixels in the pixel column are paired, one of two pixels in each pair is connected with the first data signal line and the other of the two pixels is connected with the second data signal line, two scanning signal lines respectively connected with the two pixels are simultaneously selected during one horizontal scanning period so that signal potentials are written into the two pixels from the first data signal line and the second data signal line, respectively, during each horizontal scanning period, supply of the signal potentials to the first data signal line and the second data signal line is performed after supply of preliminary potentials to the first data signal line and the second data signal line. This allows improving the display quality of a liquid crystal display in which a larger size, higher definition, or higher-speed driving etc. makes full charging of pixels difficult even when simultaneous scanning.

First and second data signal lines are provided for a column of pixels, and signal potentials of opposite polarity to each other are supplied to the data signal lines respectively. In at least one embodiment, a predetermined pixel is taken as the first pixel. A pixel other than the (2×n×i+1)-th pixel in the scanning direction is connected to a data signal line different from that connected to the previous pixel, whereas the (2×n×i+1)-th pixel is connected to the same data signal line as that connected to the previous pixel. The polarity of the signal potential supplied to each data signal line is inverted every n horizontal scanning periods. Every adjacent two scan signal lines starting from the scan signal line connected to the predetermined pixel are sequentially selected at the same time among scan signal lines. A liquid crystal display with this structure enables an increase of the pixel charging time as well as prevention of flickering.

In a transistor adapted to suppress characteristic degradation resulting from fluorine contained in a deposited film, the concentration of fluorine contained in a gate insulating film (3) is reduced to 1.0×1020 atoms/cm3 or less. As a result, the transistor can provide excellent reliability even when it is continuously driven for a long period of time at a relatively high temperature.
