또한 본 고안은 칼라 필터가 UV유기막으로 형성됨을 특징으로 한다.In addition, the present invention is characterized in that the color filter is formed of a UV organic film.
이하 본 고안의 바람직한 실시예를 첨부한 도면에 따라 더욱 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
도면은 본 고안의 액정표시소자 측단면도로서, 부호(1)은 상부기판을 나타낸다.Figure is a side cross-sectional view of the liquid crystal display device of the present invention, the reference numeral 1 denotes the upper substrate.
상부기판(1)에는 전극(2)가 형성되어 있으며, 전극(2)의 표면에는 유기 배향막(3)이 균일한 두께로 형성되어 있다.An electrode 2 is formed on the upper substrate 1, and an organic alignment layer 3 is formed on the surface of the electrode 2 with a uniform thickness.
그리고 하부기판(4)에는 상기한 구성과 동일하게 전극(5)와 유기 배향막(6)이 형성되어 있으며, 스페이서(7)에 의해 일정한 간격이 유지되면서 상하부기판(1) (4)가 에폭시(8)로 상호 접착되어 있고, 전극(2) (5)를 연결하는 은(9)가 인쇄되어 있다.In the lower substrate 4, the electrode 5 and the organic alignment layer 6 are formed in the same manner as described above, and the upper and lower substrates 1 and 4 are formed of epoxy ( 8) are bonded to each other, and silver 9 connecting the electrodes 2 and 5 is printed.
상기한 상부기판(1)의 윗면에는 편광판(10)이 부착되어 있으며, 하부기판(4)의 아래면에는 칼라 UV 유기막(11)이 형성되어 있고, 그 외측에 편광판(12)가 부착되어 있다.The polarizing plate 10 is attached to the upper surface of the upper substrate 1, the color UV organic film 11 is formed on the lower surface of the lower substrate 4, the polarizing plate 12 is attached to the outside have.
도면중 미설명부호 13은 셀내부에 액정을 주입하고난후 유동을 방지하는 봉지제를 나타낸다.In the drawing, reference numeral 13 denotes an encapsulant that prevents flow after injecting liquid crystal into the cell.
이와 같이 구성되는 본 고안의 칼라 액정 표시 소자 제조공정을 설명하면 다음과 같다.The manufacturing process of the color liquid crystal display element of this invention comprised as mentioned above is as follows.
먼저 상하부 기판(1) (4)에 ITO를 10-1000Å의 두께로 전면에 걸쳐 증착 시키고, 그 위에 감광제를 도포한후 포토에칭법으로 전극(2) (5)를 형성한다.First, ITO is deposited on the upper and lower substrates 1 and 4 over the entire surface with a thickness of 10-1000 GPa, and a photosensitive agent is applied thereon to form electrodes 2 and 5 by photoetching.
다음에 전극(2) (5)면에 유기 배향막(3) (6)을 100-3000Å의 두께로 균일하게 도포한후, 소성하여 경화시킨다.Next, the organic alignment film (3) (6) is uniformly applied to the surface of the electrode (2) (5) to a thickness of 100-3000 kPa, and then fired and cured.
그리고 유기배향막(3) (6)을 부드러운 천등으로 문질러 배향면을 형성시킨후, 스페이서(7)을 균일하게 뿌린다.After the organic alignment films 3 and 6 are rubbed with a soft cloth to form an alignment surface, the spacers 7 are evenly sprayed.
이렇게 하여 얻어진 상하부 기판(1) (4)중 어느 한면에 에폭시(8)을 인쇄하고 또다른 기판면에는 전극을 연결할 수 있는 은(9)를 인쇄한 다음, 상하부 기판(1) 4)를 조합하여 균일한 압력을 가하면서 소성을 하고, 액정을 셀내부로 주입한 후에 봉지제(13)으로 봉지한다.The epoxy (8) is printed on one of the upper and lower substrates (1) and (4) thus obtained, and the silver (9) to which the electrode can be connected is printed on the other substrate surface, and then the upper and lower substrates (1) 4 are combined. It bakes while applying a uniform pressure, and inject | pours a liquid crystal into a cell, and then seals with the sealing agent 13.
상기한 공정이 완료되면 상하부기판(1) (4)의 표면에 묻어 있는 이물질을 제거하고 상부기판(1)에 편광판(10)을 부착시킨다음, 하부기판(4)에 칼라 UV 유기막(11)을 균일한 두께로 착색하고 자외선을 일정시간 조사시켜 경화시킨후, 편광판(12)를 상기한 편광판(10)과 동일한 방향으로 부착시키는 공정에 의해 제작 완료 된다.After the above process is completed, the foreign substances on the surface of the upper and lower substrates 1 and 4 are removed, and the polarizing plate 10 is attached to the upper substrate 1, and then the color UV organic film 11 is attached to the lower substrate 4. ) Is colored in a uniform thickness, irradiated with ultraviolet rays for a certain time, and cured, and then the fabrication is completed by attaching the polarizing plate 12 in the same direction as the polarizing plate 10 described above.
이와 같이 하여 얻어진 칼라 액정 표시 소자는 특히 하부기판(4)와 편광판(12) 사이에 칼라 UV 유기막(11)이 위치되기 때문에 손상을 입지 않게 되어 표시 색상의 선명도를 높일 수 있고, 자외선으로 칼라 UV 유기막(11)을 경화시킴으로서, 스크린 인쇄법으로 표시물의 칼라 색상을 얻는 종래방식에 비하여 소성공정시간을 단축시킬 수 있는 이점이 있다.In the color liquid crystal display device thus obtained, since the color UV organic film 11 is positioned between the lower substrate 4 and the polarizing plate 12, the color liquid crystal display is not damaged, thereby increasing the sharpness of the display color. By curing the UV organic film 11, there is an advantage that the baking process time can be shortened as compared with the conventional method of obtaining the color color of the display by the screen printing method.
