Thin film transistor substrate and LCD panel
View Patent ↗A thin film transistor (TFT) substrate includes a substrate, data lines, scan lines and pixel electrodes. The data lines and the scan lines intersect each other on the substrate for defining pixel areas. The pixel electrodes are disposed in corresponding pixel areas. Each of the pixel electrodes defines at least two slits by which the pixel electrode is divided into at least two first areas and at least two second areas. The first areas and the second areas are insulated with respect to each other. The first areas are disposed diagonally and the second areas are disposed diagonally.
