ABSTRACT:
A thin film transistor (TFT) substrate that is capable of providing a wide viewing angle and high contrast ratio without a decrease is aperture ratio is presented. The TFT substrate may be, for example, used with a patterned vertical alignment (PVA) mode LCD. The TFT substrate includes gate lines and data lines extending in non-parallel directions and a pixel electrode formed in a pixel region. The pixel region has two transmission regions separated from each other by a reflection region, and at least one of the gate lines is formed in the reflection region. A storage capacitor may also be formed in the reflection region. This configuration avoids the use of a bridge region between the two transmission regions that is responsible for aperture ratio decrease in the conventional configuration.
