본 발명은 칼라 액정표시소자에 관한 것으로, 특히 각 전극에 칼라필터를 형성하고 보상 셀에도 칼라필터를 구성하여 2층 모두 구동 가능한 구조로 고해상도에 적당하도록 한 2층 구조 칼라액정 표시소자에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color liquid crystal display device, and more particularly, to a two-layered color liquid crystal display device in which a color filter is formed on each electrode and a color filter is also configured in a compensation cell so that both layers can be driven. .

제1a도 내지 c도는 종래 2층 액정표시소자 구성을 보인 단면도로서 이와 종래의 판넬 평면도인 제2도를 참조하여 종래 2층 액정표시소자 구조 및 문제점을 설명하면 다음과 같다.1a to c are cross-sectional views showing the structure of a conventional two-layer liquid crystal display device and the structure and problems of the conventional two-layer liquid crystal display device will be described with reference to FIG.

청결하고 잘 건조된 유리기판(1)(1')위에 투명전극(2)(2')을 형성하고, 상기 유리기판(1)(1')중 하부판넬 유리기판(1)의 투명전극(2)위에 칼라필터(3)를 형성하고 배향막(4)을 입힌 후 액정표시소자의 형태에 따라 임의의 각도로 러빙(Rubbing)하고 액정을 주입하여 제1a도와 동일한 구조의 구동 셀(11)을 형성한다.Transparent electrodes 2 and 2 'are formed on the clean and well-dried glass substrate 1 and 1', and transparent electrodes of the lower panel glass substrate 1 of the glass substrate 1 and 1 'are formed. 2) the color filter 3 is formed on the alignment layer 4 and the alignment layer 4 is coated, followed by rubbing at an angle according to the shape of the liquid crystal display device, and injecting the liquid crystal to drive the drive cell 11 having the same structure as in FIG. Form.

이후 제1b도와 동일한 구조의 보상 셀(12)은 상기 구동 셀(11) 구조에서 상기 투명전극(2)(2')과 하부 판넬의 칼라필터(3)가 제외된 구조로, 유리기판(1)(1')위에 배향막(4)을 입힌 후 상기 구동 셀(11)의 액정의 뒤틀림방향과 반대방향으로 뒤틀리도록 러빙 시킨 후 액정을 주입하여 구성한다.Thereafter, the compensation cell 12 having the same structure as in FIG. 1B has a structure in which the transparent electrode 2, 2 ′ and the color filter 3 of the lower panel are excluded from the driving cell 11. After the alignment film 4 is coated on the 1 ', the liquid crystal is injected by rubbing so as to be twisted in a direction opposite to the twisting direction of the liquid crystal of the driving cell 11.

상기의 과정을 통해 형성된 구동 셀(11)과 보상 셀(12)을 합착한다. 이때 상기 구동 셀(11)과 보상셀(12)이 이웃하는 구동 셀(11)의 상부 유리기판(1')의 러빙방향과 상기 보상 셀(12)의 하부 유리기판(1)의 러빙방향이 서로 90°의 각도를 갖게 합착하며, 이후 상기 구동 셀(11)의 하부 유리기판(1)에 그 하부 유리기판(1)의 러빙방향에 임의의 각도로 하여 편광판(6)을 부착하고 상기 보상 셀(1')의 상부유리기판(1)에 상기 편광판(6) 부착시와 동일하게 이웃 유리기판(1')의 러빙방향에 대해 임의의 각도로 검광판(8)을 부착하여 제1c도와 동일하게 2층구조의 액정표시소자를 제조한다. 이때 판넬 평면도는 제2도와 동일하다.The driving cell 11 and the compensation cell 12 formed through the above process are bonded together. At this time, the rubbing direction of the upper glass substrate 1 ′ of the driving cell 11 adjacent to the driving cell 11 and the compensation cell 12 and the rubbing direction of the lower glass substrate 1 of the compensation cell 12 are different from each other. The polarizing plate 6 is attached to the lower glass substrate 1 of the driving cell 11 at an arbitrary angle to the rubbing direction of the lower glass substrate 1 and then the compensation is performed. In the same manner as when the polarizing plate 6 is attached to the upper glass substrate 1 of the cell 1 ', the detector plate 8 is attached at an arbitrary angle with respect to the rubbing direction of the neighboring glass substrate 1'. In the same manner, a liquid crystal display device having a two-layer structure is manufactured. In this case, the panel plan view is the same as FIG.

상기와 같은 종래 2층구조의 액정표시소자는 구동 셀(11)과 보상 셀(12)의 굴절을 이방성편차와 상하부 기판간의 거리(△nㆍd)가 거의 같고, 액정 뒤틀리는 방향이 각각 90°로 반대이므로 구동 셀(11)을 통과한 광이 보상 셀(12)을 지나면서 광이 보상되어 원래의 편광상태가 되며, 또는 편광판(6)의 투과측방향과 검광판(8)의 투과측이 90°이면 흑표시가 가능하고 구동 셀(11)에 전압이 인가되고 칼라필터(3)가 없다고 가정하면 백표시가 가능하다. 이로인해 화소에 칼라가 있으면 표시부위에는 색상이 나타나게 된다.In the conventional two-layered liquid crystal display device, the anisotropy deviation and the distance between the upper and lower substrates are almost equal to each other in the refraction of the driving cell 11 and the compensation cell 12, and the liquid crystal twisting direction is 90 °. Since the light is reversed, the light passing through the driving cell 11 passes through the compensation cell 12 and the light is compensated to become the original polarized state, or the transmission side direction of the polarizing plate 6 and the transmission side of the analyzer 8 If it is 90 degrees, black display is possible, and if a voltage is applied to the drive cell 11 and there is no color filter 3, a white display is possible. As a result, when a pixel has a color, a color appears on the display portion.

그러나, 상기와 같은 종래 2층구조의 액정표시소자에서 보상 셀은 보상기능만 하며 구동 셀에만 칼라필터가 구성되어 구동화소가 한정되어 있고 각 화소에 있는 칼라필터 또한 한정되어 있으므로 해상도가 떨어져 소자의 특성을 저하시키는 문제점이 있었다.However, in the liquid crystal display device of the conventional two-layer structure as described above, the compensation cell has only a compensation function, and the color filter is configured only in the driving cell so that the driving pixel is limited and the color filter in each pixel is also limited. There was a problem of deteriorating characteristics.

본 발명은 상기와 같은 종래의 문제점을 감안하여 창안한 것으로, 구동 셀과 보상 셀 모두 구동이 가능한 2층구조로 형성하고 각 전극에 각 셀의 칼라필터를 서로 어긋나게 배열함으로써 해상도를 증가시켜 소자의 특성을 개선함에 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional problems, and has a two-layer structure capable of driving both a driving cell and a compensating cell, and increases the resolution by arranging color filters of each cell on each electrode so that the resolution is increased. The purpose is to improve the properties.
