FFS mode liquid crystal display device with viewing angle control region and method of fabricating the same
First Claim
Patent Images
1. A method for fabricating of a liquid crystal display device including liquid crystal display molecules, the method comprising:
- forming a gate electrode, a gate pad and a data pad on a substrate;
forming a gate insulation layer and forming a source and drain electrode on the gate electrode;
forming a first passivation layer and a photoacrylic layer on an entire surface of the substrate, and forming a contact hole therein;
forming a common electrode for a display control region where liquid crystal molecules are inclined, and forming a common electrode for a viewing-angle control region where liquid crystal molecules are inclined in horizontal and vertical directions;
forming a second passivation layer on the entire surface of the substrate, and forming a contact hole therein; and
forming a pixel electrode in the display control region, and forming a viewing-angle control electrode in the viewing-angle control region corresponding to each display control region, to incline the liquid crystal molecules in vertical and horizontal directions.

Abstract
A liquid crystal display device and method of fabricating the device where the device can control a viewing angle in all directions without forming a white pixel. The liquid crystal display device includes a display control region that is controlled such that liquid crystal molecules are inclined and a viewing-angle control region that is controlled such that liquid crystal molecules are aligned in a horizontal or vertical direction, where a control voltage is supplied through a viewing angle control line independent of a common line for the display control region.
