Description
본 발명은 액정표시장치에 관한 것으로서, 보다 상세하게는 TFT LCD 디스플레이에 있어서, 고투과, 광시야 및 색팀이 발생하지 않는 액정디스플레이 모드인 2중 도메인 FFS 모드의 액정표시장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device of a dual domain FFS mode, which is a liquid crystal display mode in which high transmittance, wide field of view and color team do not occur in a TFT LCD display.
종래기술에 따른 2중 도메인 FFS(Fringe Field Switching) 모드 액정표시장치를 도 1 및 도 2를 참조하여 설명하면 다음과 같다.A dual domain FFS mode liquid crystal display according to the related art will be described with reference to FIGS. 1 and 2 as follows.
도 1은 종래기술의 일 실시예에 따른 2중 도메인 FFS 모드 액정 표시장치의 평면도를 나타낸 도면이다.1 is a plan view illustrating a dual domain FFS mode liquid crystal display according to an exemplary embodiment of the prior art.
게이트버스라인(11) 및 공통버스라인(13)은 불투명 금속이며, 도시되어 있지는 않지만 투명한 금속으로 이루어진 플레이트형 상대전극이 한 서브화소 단위로 화소전극(17)의 하단부에 게이트 절연막을 사이에 두고 중첩되어 있으며, 상대전극과 공통버스라인(13)은 연결되어 있다.The gate bus line 11 and the common bus line 13 are opaque metals, and a plate-type counter electrode made of a transparent metal, although not shown, is disposed on the lower end of the pixel electrode 17 in units of one subpixel, with a gate insulating film interposed therebetween. The counter electrode and the common bus line 13 are connected to each other.
도 1에 도시된 바와같이, 화소전극(17)은 플레이트형 투명한 금속으로 이루어져 있으며, 공통버스라인(13)을 사이에 두고 서로 상하 대칭적으로 슬릿형으로 다수개의 개구영역(19)이 존재하며, 이로 인하여 드러나 있는 상대전극과 화소전극(17)사이에 프린지 필드가 발생하게 된다.As shown in FIG. 1, the pixel electrode 17 is made of a plate-shaped transparent metal, and a plurality of opening regions 19 exist in a slit shape up and down symmetrically with a common bus line 13 therebetween. As a result, a fringe field is generated between the exposed counter electrode and the pixel electrode 17.
대략, 슬릿형의 개구영역(19)의 폭은 대략 2에서 6 μm사이의 값을 가지며, 개구영역과 개구영역사이의 개구되어 있지 않은 슬릿의 폭 또한 대략 2에서 6 μm사이의 값을 가지게 하므로, 화소전극과 상대전극사이에 프린지필드에 의하여 액정을 구동한다.Approximately, the width of the slit-shaped opening region 19 has a value between approximately 2 and 6 μm, and the width of the unopened slit between the opening region and the opening region also has a value between approximately 2 and 6 μm. The liquid crystal is driven by the fringe field between the pixel electrode and the counter electrode.
그러나, 도 1에서와 같이, 종래의 설계구조를 가질 경우, "A"영역에 의한 투과가 이루어지고 있지 않아 개구영역으로 활용할 수 없는 문제가 있다. 그 이유로는 공통버스라인(13)은 불투명 금속으로 이루어져 있기 때문에 투과영역으로 활용을 하지 못할 지라도, "A"영역의 공통버스라인을 제외한 영역들에서는 투과율을 발생해야 하지만, 상대전극이 화소전극의 비개구영역의 하단부에 중첩되어 있기 때문에 프린지필드가 발생하지 않게 되어, 결국은 투과영역으로 활용할 수 없는 영역이 된다.However, as shown in FIG. 1, when having a conventional design structure, there is a problem that the transmission by the "A" region is not made and thus cannot be used as an opening region. For this reason, although the common bus line 13 is made of an opaque metal and thus cannot be used as a transmission region, the transmittance should be generated in regions except for the common bus line of the “A” region, but the counter electrode is formed of the pixel electrode. Since the fringe field does not occur because it overlaps with the lower end of the non-opening area, the area becomes unusable as a transmission area.
또한, 도 2는 종래의 일실시예로서, 2중 도메인의 투과율을 향상시키고자 "A"영역에 화소전극(27)의 개구영역(29)을 두어 이 영역에서도 플린지 필드가 발생하도록 하여 투과영역으로 활용하고자 한 의도에서 설계되어진 구조이다.In addition, FIG. 2 illustrates a conventional embodiment, in which an opening region 29 of the pixel electrode 27 is disposed in an “A” region in order to improve the transmittance of the dual domain so that the fringe field is generated in this region. It is a structure designed with the intention to use it as an area.
그러나, 도 2에서와 같이, "A"영역에도 화소영역을 개구하여 상대전극과 플린지필드를 유도하였으나, 이 영역에서도 투과율을 발생하지 않았다. 투과율을 발생시키기 위해서는 사선으로 투정각도를 유지하게끔 설계되어진 화소전극의 개구영역 및 개구되지 않은 영역에서는 직교하는 방향으로 프린지필드가 발생한다.However, as shown in Fig. 2, the pixel region was also opened in the "A" region to induce the counter electrode and the fringe field, but no transmittance was generated in this region. In order to generate the transmittance, the fringe field is generated in the orthogonal direction in the opening area and the non-opening area of the pixel electrode which are designed to maintain the angle of permeation diagonally.
따라서, 전압무인가시 러빙에 의해 초기 배향되어 있던 액정들이 프린지 필드방향으로 회전하여 투과율이 발생하나, 도 2에서는 공통버스라인(23)이 게이트버스라인(21)과 평행하게 배치되어 있고, 화소를 상하 2등분하고 있다.Accordingly, although the liquid crystals that were initially oriented by rubbing in the absence of voltage rotate in the fringe field direction, transmittance occurs. In FIG. 2, the common bus line 23 is disposed in parallel with the gate bus line 21, and the pixel is moved. It is divided into two top and bottom.
또한, 화소전극(27)의 개구영역(29)의 상당부분을 공통버스라인(23)이 중첩됨으로 인하여 화소전극 슬릿과 개구되어 드러나 있는 상대전극간에 슬릿과 직교하는 방향으로 프린지필드가 발생하여야 하나, 상당부분이 중첩되어 있는 공통버스라인에 의하여 필드의 왜곡이 발생하여 액정에 제대로 된 유전체 토크(dielectric torque)를 주지 못하므로 액정이 회전하지 않게 되므로써 투과율이 발생하지 않는 것을 발견할 수 있었다.In addition, since the common bus line 23 overlaps a substantial portion of the opening region 29 of the pixel electrode 27, the fringe field should be generated in a direction orthogonal to the slit between the pixel electrode slit and the counter electrode exposed. As a result, distortion of the field occurs due to the overlapping common bus line, which does not give a proper dielectric torque to the liquid crystal, so that the liquid crystal does not rotate, and thus no transmittance occurs.
따라서, 도 1 및 이를 개선하기 위한 도 2에서와 같은 종래의 화소설계구조를 가질 경우에, 한 화소내에서 불투명 금속인 공통버스라인을 포함한 "A"영역에서 투과율이 발생하지 않는 문제점을 안게 된다.Therefore, in the case of having the conventional pixel design structure as shown in FIG. 1 and FIG. 2 to improve the same, the transmittance does not occur in the area "A" including the common bus line which is an opaque metal in one pixel. .
이에 본 발명은 상기 종래기술의 제반 문제점을 해결하기 위하여 안출한 것으로서, 공통버스라인의 위치를 최적화하여 이중 도메인 FFS 모드의 개구영역내 의 액정을 보다 효율적으로 트위스트시켜 투과율을 향상시킬 수 있는 2중 도메인 FFS 모드의 액정표시장치를 제공함에 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art, and it is possible to optimize the position of the common bus line to more efficiently twist the liquid crystal in the opening region of the dual domain FFS mode to improve the transmittance. An object of the present invention is to provide a liquid crystal display device in a domain FFS mode.

(실시예)(Example)
이하, 본 발명에 따른 2중 도메인 FFS 모드의 액정표시장치를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, a liquid crystal display of a dual domain FFS mode according to the present invention will be described in detail with reference to the accompanying drawings.
도 3은 본 발명에 따른 2중 도메인 FFS 모드 액정 표시장치의 평면도를 나타낸 도면이다.3 is a plan view illustrating a dual domain FFS mode liquid crystal display according to the present invention.
도 4는 본 발명에 따른 도 3의 "B"영역의 확대평면도이다.4 is an enlarged plan view of region "B" of FIG. 3 in accordance with the present invention.
본 발명에서는, 도 3에서와 같이, 불투명 금속으로 이루어져 있는 공통버스라인(33)의 적어도 1/3 이상을 플레이트 형태의 투명전극으로 이루어진 화소전극(37)의 개구되지 않은 비개구영역이 덮고 있으며, 화소전극의 개구되어 있는 공통버스라인(33)측의 인접영역, 즉 "C"영역이 공통버스라인과 중첩되지 않고 드러나 있는 화소설계 구조를 제안한다.In the present invention, as shown in FIG. 3, at least one third or more of the common bus line 33 made of an opaque metal is covered by an unopened non-opening region of the pixel electrode 37 made of a plate-shaped transparent electrode. A pixel design structure is proposed in which adjacent areas on the common bus line 33 side of the pixel electrode, that is, "C" area, are exposed without overlapping the common bus line.
또한, 도 4는 도 3에 도시된 "B"영역의 확대한 그림 및 "A"영역에서 어떻게 액;정이 회전하므로 공통버스라인을 제외한 "A"영역에서 투과율이 발생하는지를 보여 주기 위한 그림이다.4 is an enlarged view of the area "B" shown in FIG. 3 and how the liquid crystal is rotated in the area "A", so that the transmittance occurs in the area "A" except the common bus line.
도 4에서와 같이, 도 3에서 "C"영역에서는 공통버스라인에 영향을 받지 않는다. 그 이유로는 투명금속으로 이루어진 화소전극면이 모두 불투명 메탈로 이루어진 공통버스라인을 덮고 있기 때문이다.As shown in FIG. 4, in the “C” region of FIG. 3, the common bus line is not affected. The reason is that the pixel electrode surfaces made of transparent metal all cover the common bus line made of opaque metal.
따라서, L'(화소전극의 개구영역의 내측면과 공통버스라인이 중첩되어 있지 않은 영역)에서는 공통버스라인이 화소전극면에 의하여 모두 덮여져 있기 때문에 필드왜곡이 발생하지 않고 투과율이 발생한다.Therefore, in L '(the region where the inner surface of the opening area of the pixel electrode and the common bus line do not overlap), since the common bus line is covered by the pixel electrode surface, field distortion does not occur and transmittance occurs.
그러나, L(화소전극의 개구영역의 내측면의 길이)에서 L'를 제외한 영역은 공통버스라인이 화소전극의 개구영역과 중첩되어 있으므로 인하여 사선 방향으로 이루어져 있는 필드방향(화소전극의 개구가 사선으로 이루어져 있기 때문)을 왜곡하게 되며, 원칙적으로는 이 부분에서 투과율이 발생하지 않아야 한다.However, in the area except L 'in L (the length of the inner surface of the opening area of the pixel electrode), the common bus line overlaps the opening area of the pixel electrode, so that the field direction (the opening of the pixel electrode is diagonal) ), And in principle, the transmittance should not occur in this part.
그러나, 액정 상호간의 상호작용(interaction) 및 탄성력에 의하여 도 4의 화살표 방향과 같이, "C"영역에서 프린지필드에 의한 액정의 유전체 토크 (dielectric torque)에 의하여 먼저 회전한 액정들이 바로 인접한 영역의 액정들을 순차적으로 회전시키기 되어 이 부분의 모든 액정들을 회전시키게 된다.However, due to the interaction and elastic force between the liquid crystals, the liquid crystals rotated first by the dielectric torque of the liquid crystal by the fringe field in the "C" region as shown by the arrow direction of FIG. The liquid crystals are rotated sequentially to rotate all liquid crystals in this portion.
따라서, 불투명 전극으로 이루어져 있는 공통버스라인상단부를 제외한 "A"영역의 모든 부분에서 투과율이 발생하게 된다.Therefore, the transmittance is generated in all parts of the "A" region except for the upper part of the common bus line composed of the opaque electrodes.
이와 같은 2중 도메인 FFS 모드 액정표시소자를 가질 경우 불투명메탈로 이루어진 공통버스라인이 화소전극 전면에 의하여 덮여 있으므로 인해, 화소전극과 상대전극사이의 프린지 필드에 영향을 줄 수 없기 때문에 전압 인가시 이 영역에서부터 투과율이 발생하여 도 4의 화살표 방향으로 순차적으로 액정이 구동 및 투과율이 발생하므로 "A"영역에서 불투명 금속으로 이루어진 공통버스라인 상단면을 제외한 전 영역에서 투과율이 발생하므로, 투과율의 향상뿐 아니라, 액정의 회전을 좀 더 원활히 할 수 있기 때문에 응답시간 특성 등에서도 효과를 볼 수 있다. 즉, 본 발명을 통하여 2중 도메인 FFS 액정표시소자의 화소설계를 최적화하므로써 투과율의 향상 및 응답시간 등의 전기광학 특성의 향상과 더블어 백라이트 수, 투과율 향상 필름 등을 줄일 수 있어 비용절감 효과를 기대할 수 있다.In the case of the dual domain FFS mode liquid crystal display device, since the common bus line made of opaque metal is covered by the front surface of the pixel electrode, the fringe field between the pixel electrode and the counter electrode cannot be affected. Since the transmittance is generated from the region and the liquid crystal is driven and transmitted in the direction of the arrow in FIG. 4, the transmittance is generated in all regions except the upper surface of the common bus line made of opaque metal in the "A" region, thereby improving the transmittance. In addition, since the liquid crystal can be rotated more smoothly, the response time can be also effective. In other words, by optimizing the pixel design of the dual domain FFS liquid crystal display device through the present invention, it is possible to improve the electro-optic characteristics such as the improvement of the transmittance and the response time, the number of double backlights, the transmittance improvement film, etc. Can be.
