다음으로, 상기 상부기판(30)과 하부기판(20) 사이에 충진되는 액정의 배향특성에 따라 상/하부기판(30, 20)에 배향막(alignment film, 미도시)을 형성하는 과정을 거치게 된다.Next, an alignment film (not shown) is formed on the upper and lower substrates 30 and 20 according to the alignment characteristics of the liquid crystal filled between the upper substrate 30 and the lower substrate 20. .

다음으로, 상기 상부기판(30)과 하부기판(20)을 소정의 접착제(sealant)로 부착한 후, 상기 부착된 두 기판 사이의 공간에 임의의 액정(50)을 충진하여 줌으로써 액정패널이 완성된다.Next, after attaching the upper substrate 30 and the lower substrate 20 with a predetermined adhesive, a liquid crystal panel is completed by filling an arbitrary liquid crystal 50 in the space between the two substrates attached thereto. do.

A polarizing plate having a function such as static) was manufactured and attached to the outside of the upper substrate 30 and the lower substrate 20, respectively.

이하, 첨부 도면을 참조하여 본 발명의 액정표시장치에 대하여 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, the liquid crystal display device of this invention is demonstrated with reference to an accompanying drawing.

본 발명의 액정표시장치는 인-셀 편광판(in-cell polarizer)을 적용하는 경우, 눈부심 방지, 반사 방지 및 정전기 방지 등의 처리를 기판에 직접할 수도 있으며, 또는 기판에 표면 처리 필름/층을 도입할 수도 있다.When the in-cell polarizer is applied to the liquid crystal display of the present invention, anti-glare, anti-reflection, and anti-static treatment may be directly performed on the substrate, or the substrate may be provided with a surface treatment film / layer. You can also introduce.

도 3은 본 발명의 일 실시예에 적용될 눈부심 방지, 반사 방지 필름의 층 구조를 나타낸 실시예이다.Figure 3 is an embodiment showing the layer structure of the anti-glare, anti-reflection film to be applied to one embodiment of the present invention.

도시된 바와 같이, 인-셀 편광판(95)이 내부에 형성된 기판(90)에 눈부심 방지 필름(100)은 트리아세틸 셀룰로스를포함하는 투명 지지체(110), 눈부심 방지 경질 피복층(120), 그리고 저굴절률층(130)의 순서로 된 층 구조를 갖는다. 매트 입자(140)는 눈부심 방지 경질 피복층(120)에 분산되어 있다. 눈부심 방지 경질 피복층(120)은 복수개의 층으로 구성될 수도 있다.As shown, the anti-glare film 100 on the substrate 90 in which the in-cell polarizer 95 is formed includes a transparent support 110 containing triacetyl cellulose, an anti-glare hard coat layer 120, and low It has a layer structure in the order of the refractive index layer 130. The mat particles 140 are dispersed in the anti-glare hard coat layer 120. The anti-glare hard coating layer 120 may be composed of a plurality of layers.

또한, 눈부심 방지 특성을 갖지 않는 경질 피복층(도면에는 도시하지 않음)이 필름 강도의 제공을 위해 피복될 수도 있지만, 항상 필요한 것은 아니다.In addition, a hard coat layer (not shown) that does not have anti-glare properties may be coated to provide film strength, but this is not always necessary.

본 발명에 사용되는 '경질 피복층'은 눈부심 방지 경질 피복층과 눈부심 방지 특성을 갖지 않은 경질 피복층을 모두 포함한다.The 'hard coating layer' used in the present invention includes both an anti-glare hard coating layer and a hard coating layer having no anti-glare property.

상기 눈부심 방지 경질 피복층의 굴절율은 1.50 내지 2.00이 바람직하고, 저굴절률층의 굴절률은 1.35 내지 1.45가 바람직하다. 투명 지지체로서 사용되는 트리아세틸 셀룰로스의 굴절률은 1.48이다.The refractive index of the anti-glare hard coating layer is preferably 1.50 to 2.00, and the refractive index of the low refractive index layer is preferably 1.35 to 1.45. The refractive index of triacetyl cellulose used as the transparent support is 1.48.

본 발명의 눈부심 방지 필름은 헤이즈 값이 3% 이상이 바람직하고, 3 내지 15%가 더욱 바람직하다. 눈부심 방지 특성과헤이즈 값이 반드시 선형적으로 대응하는 것은 아니지만, 헤이즈 값이 3% 이하이면 충분한 눈부심 방지 특성을 가진 눈부심 방지 필름을 얻을 수 없다. 한편, 헤이즈 값이 너무 크면, 필름 표면 또는 필름내측의 광산란이 강하고, 그 결과 선명도의 저하 및 화상의 백색화와 같은 문제가 발생하여 바람직하지 않다.The anti-glare film of the present invention preferably has a haze value of 3% or more, more preferably 3 to 15%. Although the anti-glare property and the haze value do not necessarily correspond linearly, when the haze value is 3% or less, an anti-glare film having sufficient anti-glare property cannot be obtained. On the other hand, if the haze value is too large, light scattering on the film surface or inside of the film is strong, and as a result, problems such as lowering of sharpness and whitening of the image occur, which is not preferable.

도 4는 도 3의 눈부심 방지 및 반사 방지 필름이 부착된 액정표시장치를 개략적으로 도시한 단면도이다.4 is a schematic cross-sectional view of the liquid crystal display device having the anti-glare and anti-reflection film of FIG.

또한, 다른 응용예에서는 상기 상부기판(200) 위에 눈부심 방지 및 반사 방지 필름을 부착하는 대신, 노출된 상부기판(200)의 표면을 에칭(Etching) 또는 샌딩(Sanding)등을 이용하여 직접 처리할 수도 있다.In addition, in another application, instead of attaching an anti-glare and anti-reflection film on the upper substrate 200, the surface of the exposed upper substrate 200 may be directly processed by etching or sanding. It may be.

게다가, 상기 상부기판(200)의 외부 표면을 처리하는 또 다른 응용예로는 반반사 및 정전기 방지 재료를 코팅(Coating) 또는 인쇄하는 방법이 있을 수 있다.In addition, another application for treating the outer surface of the upper substrate 200 may be a method of coating or printing antireflective and antistatic materials.
