Problems solved by technology

[0032] First, the prior art LCD device is constructed to have white sub-pixels; however, white resin needs to be newly formed, and the driving operation of the white sub-pixels is different from that of the prior art
[0033] Although the visibility of a specific direction in LCD devices can be improved due to the "<" shaped common electrode, it is not possible to achieve the privacy of the display when it is particularly required

Embodiment Construction

[0066] Preferred embodiments of the present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. Wherever possible, the same reference numbers will be used in the different drawings to refer to the same or like parts.

[0067] The LCD device according to the present invention will be described in more detail below.

[0068] figure 1 It is a schematic plan view of a pixel in the FFS mode LCD device according to the first embodiment of the present invention. exist figure 1 Among them, one pixel includes the display control area 10 and the viewing angle control area 20 .

[0069] The display control region 10 controls the tilt direction of the liquid crystal molecules using the common electrode 11 exposed in the shape of "<", thereby adjusting the tilt direction of the liquid crystal.

[0070] Each RGB pixel includes a display control area 10 having a common electrode 11 exposed in a "<" shape, and a pixel electrode...

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.

Description

[0001] The present invention claims the benefit of priority from Japanese Patent Applications No. JP2005-379770 and No. JP2005-377202 filed on December 28, 2005, the entire contents of which are incorporated herein by reference. technical field [0002] The present invention relates to a liquid crystal display (LCD) device capable of controlling the viewing angle and a manufacturing method thereof, in particular to a fringe field switching (FFS) mode LCD device. Background technique [0003] Liquid crystal displays, especially those employing thin film transistors (TFTs), have been widely used in applications ranging from mobile phones to large-size televisions. [0004] One of these liquid crystal displays is a personal display device, and its display screen is required to be viewable by the user of the personal display device, and not be seen by others from the side of the personal display device. [0005] Preferably, the personal display device is constructed so that the ...
