Problems solved by technology

Although the reduction in charge rate can be compensated by increasing the storage capacitance, the increase in response time can be compensated by increasing the width of the notch or protrusion, but this will cause a decrease in the aperture ratio.

Embodiment Construction

[0061] The present invention will be described more fully hereinafter with reference to the accompanying drawings that show preferred embodiments of the invention. Of course, the present invention can be implemented in many different forms and is not limited to the embodiments set forth herein.

[0062] In the drawings, the thickness of layers, films and regions are exaggerated for clarity. The same reference numerals denote the same elements throughout. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" another element, it can be directly on the other element or intervening elements may also be present. However, when an element is referred to as being "directly on" another element, there are no intervening elements present.

[0063] Now, a liquid crystal display (LCD) and a thin film transistor (TFT) array panel of the LCD according to an embodiment of the present invention will be described with reference to ...

Abstract

A liquid crystal display is provided, which includes a thin film transistor array panel and a common electrode panel facing the thin film transistor array panel. The thin film transistor array panel includes a first gate line; a data line intersecting the gate line; a first thin film transistor including a gate electrode connected to the gate line, a source electrode connected to the data line, and a drain electrode; a first pixel electrode connected to the drain electrode; and a capacitor electrode overlapping at least one of the pixel electrode and the drain electrode with interposing an insulator. The common electrode panel includes a common electrode that faces the pixel electrode and has an opening facing at least one of the drain electrode and the capacitor electrode.

Description

technical field [0001] The invention relates to a liquid crystal display and a thin film transistor array board thereof. Background technique [0002] Liquid crystal displays (LCDs) are among the most widely used flat panel displays. An LCD includes a liquid crystal (LC) layer sandwiched between a pair of panels provided with field generating electrodes. The LC layer is placed in an electric field generated by the electrodes, and changes in the field strength can change the molecular orientation of the LC layer, which in turn changes the polarization of light passing through the liquid crystal layer. A properly positioned polarizer can change the transmittance of light based on the polarization of the light. [0003] One measure of LCD quality is the viewing angle, which is defined by the angle at which the LCD exhibits a predetermined contrast. Various techniques for enlarging the viewing angle have been proposed, including techniques of using vertically aligned LC layer...
