본 발명은 반사형 액정표시장치의 제조방법에 관한 것으로, 보다 상세하게 는, 액정층을 인쇄 방식으로 형성하는 반사형 액정표시장치의 액정층 형성방법에 관한 것이다. The present invention relates to a method of manufacturing a reflective liquid crystal display device, and more particularly, to a liquid crystal layer forming method of a reflective liquid crystal display device in which a liquid crystal layer is formed by a printing method.

액정표시장치(Liquid Crystal Display)는 CRT(Cathod-ray tube)를 대신하여 개발되어져 왔다. 특히, 박막트랜지스터 액정표시장치는 휴대형 단말기기의 정보표시기, 노트북 PC의 화면표시기, 랩탑 컴퓨터의 모니터 등에서 각광 받고 있는 바, 상기 CRT를 대체할 수 있는 표시장치로 산업상 그 활용도가 매우 높아져가고 있다. Liquid crystal display (Liquid Crystal Display) has been developed in place of the CRT (Cathod-ray tube). In particular, the thin film transistor liquid crystal display device has been in the spotlight in the information display of a portable terminal device, the screen display of a notebook PC, the monitor of a laptop computer, etc., and thus, the utilization of the thin film transistor as a display device that can replace the CRT has been very high. .

이러한 액정표시장치의 백라이트의 사용 유무에 따라 투과형과 반사형으로 분류되는데, 백라이트의 사용없이 자연광을 그대로 이용하여 화상을 표시하는 반사형 액정표시장치는, 백라이트가 갖는 문제, 즉, 자체 무게, 두께 및 가격 등의 측면을 고려할 때, 그 이용이 점차 확대되고 있는 실정이다. The liquid crystal display is classified into a transmissive type and a reflective type according to the use of a backlight. A reflective liquid crystal display device that displays an image using natural light without using a backlight has a problem that the backlight has, namely, its own weight and thickness. Considering aspects such as price and price, the use thereof is gradually expanded.

예컨데, 반사형 액정표시장치는 백라이트가 필요치 않기 때문에 저소비 전력이 요구되는 휴대용 표시 소자에 매우 유용하며, 휴대 전화와 휴대 기기의 시장이 넓어짐에 따라 그 수요가 점차 증가되고 있다. For example, a reflective liquid crystal display device is very useful for a portable display device that requires low power consumption because a backlight is not required. As the market of mobile phones and portable devices expands, the demand is gradually increased.

이와 같은 반사형 액정표시장치는, 도 1에 도시된 바와 같이, 박막트랜지스터(TFT) 및 반사전극(3)을 갖는 하부기판(10a)과 컬러필터(5) 및 상대전극(6)을 갖는 상부기판(10b)이 수 개의 액정분자들을 포함한 액정층(10c)의 개재하에 합착된 구조이며, 여기서, 상기 반사전극(3)은 광효율과 시야각을 개선하기 위해 요철을 갖도록 형성되고, 액정층(10c)은 진공 상태에서 모세관 현상을 이용하여 기판들 사이 공간에 액정을 주입하는 것에 의해 형성된다. 미설명된 도면부호 1 및 4는 제1 및 제2유리기판, 2는 레진막, 3a는 제1반사전극, 3b는 제2반사전극을 나타낸다.As shown in FIG. 1, the reflective liquid crystal display device includes a lower substrate 10a having a thin film transistor TFT and a reflective electrode 3, an upper portion having a color filter 5, and a counter electrode 6. The substrate 10b has a structure in which the substrate 10b is bonded under the interposition of the liquid crystal layer 10c including several liquid crystal molecules, wherein the reflective electrode 3 is formed to have unevenness to improve light efficiency and viewing angle, and the liquid crystal layer 10c. ) Is formed by injecting a liquid crystal into the space between the substrates using a capillary phenomenon in a vacuum state. Unexplained reference numerals 1 and 4 denote first and second glass substrates, 2 resin films, 3a a first reflection electrode, and 3b a second reflection electrode.

그러나, 진공 상태에서의 모세관 현상을 이용하여 액정층을 형성하는 종래의 방법은 반사전극이 요철을 갖도록 형성된 것과 관련하여 통상의 액정 주입 장비로는 반사전극에 요철이 없는 경우와 비교해서 3배 이상의 공정 시간이 소요되며, 이에 따라, 생산성 측면에서 곤란함이 있다. However, the conventional method of forming the liquid crystal layer by using the capillary phenomenon in a vacuum state is three times or more compared with the case where the reflective electrode does not have irregularities with respect to the case where the reflective electrode is formed to have irregularities. The process takes time, and therefore, there is a difficulty in terms of productivity.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 공정 소요 시간을 대폭적으로 줄일 수 있는 반사형 액정표시장치의 액정층 형성방법을 제공함에 그 목적이 있다. Accordingly, an object of the present invention is to provide a method for forming a liquid crystal layer of a reflective liquid crystal display device which can significantly reduce the process time required.

상기와 같은 목적을 달성하기 위한 본 발명의 반사형 액정표시장치의 액정층 형성방법은, 소정 점도를 갖는 모노머와 액정분자들의 혼합액을 소정 형상으로 패터닝된 APR(Asahikasei Photosensitive Resin) 플레이트에 전사시키는 단계; 상기 액정분자와 모노머의 혼합액이 전사된 APR 플레이트를 하부기판 상에 배치시키는 단계; 상기 APR 플레이트에 전사된 혼합액이 상기 하부기판 상에 도포되도록 상기 APR 플레이트를 가압하는 단계; 및 상기 하부기판으로부터 상기 APR 플레이트를 탈착시키는 단계를 포함하는 것을 특징으로 하며, 여기서, 상기 모노머와 액정분자는 3∼80 : 1 의 비율로 혼합한다. In the liquid crystal layer forming method of the reflective liquid crystal display device of the present invention for achieving the above object, the step of transferring the mixed liquid of the monomer and the liquid crystal molecules having a predetermined viscosity to an APR (Asahikasei Photosensitive Resin) plate patterned in a predetermined shape ; Disposing an APR plate on which the liquid mixture of the liquid crystal molecules and the monomer has been transferred on a lower substrate; Pressing the APR plate so that the mixed solution transferred to the APR plate is applied onto the lower substrate; And detaching the APR plate from the lower substrate, wherein the monomer and the liquid crystal molecules are mixed at a ratio of 3 to 80: 1.

본 발명에 따르면, 인쇄 방식으로 액정층을 형성하기 때문에 종래와 비교해서 공정 소요 시간을 대폭적으로 줄일 수 있으며, 따라서, 생산성을 향상시킬 수 있다. According to the present invention, since the liquid crystal layer is formed by the printing method, the time required for the process can be significantly reduced as compared with the conventional one, and therefore the productivity can be improved.

In this state, as shown in FIG. 2A, a monomer (monomer) 11 having a predetermined viscosity and several liquid crystal molecules 12 have a predetermined ratio, preferably a ratio of monomers and liquid crystal molecules 3 to 80: 1. The mixed liquid 20 mixed with the above is prepared, and the mixed liquid 20 is uniformly transferred to an Asahikasei Photosensitive Resin (APR) plate patterned into a predetermined shape according to a known technique, as shown in FIG. 2B.

여기서, 상기 혼합액(20)의 전사는 폴리이미드 도포(polyimide coating) 장비를 이용하여 전사시킨다. 자세하게, 도 3에 도시된 바와 같이, 노즐(51)로부터 모노머와 액정분자의 혼합액(20)을 제1롤(52)에 분사시키면, 이렇게 분사된 혼합액(20)이 상기 제1롤(52)과 맞물려 회전하는 제2롤(53)에 전달된 후, 상기 제2롤(53)과 맞물려 회전하는 판동(54)에 전달되고, 이때, 판동(54)의 외주면 상에 APR 플레이트(30)를 배치시킴으로써, 상기 혼합액(20)의 APR 플레이트(30)로의 전사가 이루어진다. Here, the transfer of the mixed solution 20 is transferred using a polyimide coating equipment. In detail, as shown in FIG. 3, when the mixed liquid 20 of the monomer and the liquid crystal molecules is sprayed onto the first roll 52 from the nozzle 51, the mixed liquid 20 thus injected is the first roll 52. After being transmitted to the second roll 53 in engagement with the rotation, it is transmitted to the rotating plate 54 is engaged with the second roll 53, at this time, the APR plate 30 on the outer peripheral surface of the plate 54 By arranging, transfer of the mixed solution 20 to the APR plate 30 is performed.

계속해서, 상기 모노머(11)와 액정분자(12)의 혼합액(20)을 전사된 APR 플레이트(30)를, 도 2c에 도시된 바와 같이, 하부기판(40) 상에 배치시킨 상태에서, 상기 APR 플레이트(30)를 가압하여 상기 APR 플레이트(30)에 전사된 모노머(11)와 액정분자(12)의 혼합액(20)을 상기 하부기판(40) 상에 도포시킨다. Subsequently, in the state where the APR plate 30 to which the mixed liquid 20 of the monomer 11 and the liquid crystal molecules 12 are transferred is placed on the lower substrate 40 as shown in FIG. The APR plate 30 is pressed to apply the mixed liquid 20 of the monomer 11 and the liquid crystal molecules 12 transferred to the APR plate 30 onto the lower substrate 40.

그리고나서, 상기 APR 플레이트를 하부기판(40)으로부터 탈착시켜, 도 2d에 도시된 바와 같이, 상기 하부기판(40) 상에 액정층(50)을 형성한다. Then, the APR plate is detached from the lower substrate 40 to form the liquid crystal layer 50 on the lower substrate 40 as shown in FIG. 2D.

이후, UV 조사를 통해 실 패턴을 경화시켜 액정층(50)을 밀봉하고, 그리고나서, 상부기판의 합착 및 편광판의 부착을 통해 반사형 액정표시장치의 제조를 완성한다. Subsequently, the seal pattern is cured by UV irradiation to seal the liquid crystal layer 50, and then the manufacturing of the reflective liquid crystal display device is completed by bonding the upper substrate and attaching the polarizing plate.
