Abstract

A polarizing plate protection film for a liquid crystal display device is provided to reduce assembling time without a process of attaching a detached tape and prevent inflow of foreign matters by integrating a detached part at one end of the film and combining a polarizing plate with a liquid crystal panel by pulling down the detached part. A liquid crystal display device comprises a liquid crystal panel(100), a backlight unit(200), polarizing plates(300), and polarizing plate protection films(400). The liquid crystal panel includes liquid crystal cells which are arranged like a matrix between upper and lower glass substrates, and switch devices for switching signals supplied to the liquid crystal cells. The backlight unit has a driving circuit part, a lamp, a reflector, a light guide, diffusers, and a sheet of a prism for supplying light beam to the liquid crystal panel. The polarizing plates are placed at upper and lower sides of the two glass substrates of the liquid crystal panels. The polarizing plates convert polarizing features of the light beam of the backlight unit. The polarizing plate protection films protect the polarizing plates. A detached part(410), which extends from one end of the polarizing plate protection film, is pulled down to remove the film and to combine the polarizing plate with the liquid crystal panel.

본 발명은 액정표시장치의 편광판 보호필름에 관한 것이다.The present invention relates to a polarizing plate protective film of a liquid crystal display device.

최근 액정표시장치(Liquid Crystal Display : LCD)는 경량, 박형, 저소비 전력구동 등의 특징과 함께 액정 재료의 개량 및 미세화소 가공기술의 개발에 의해 화질이 개선되고 있으며, 또한 그 응용범위가 점차 넓어지고 있는 추세이다. 이러한 액정표시장치는 액정패널과 상기 액정패널을 구동하기 위한 구동회로부, 상기 액정패널에 광빔을 공급하는 백라이트유닛 및 편광판으로 구성된다.Recently, the liquid crystal display (LCD) has been improved in quality due to the improvement of liquid crystal materials and the development of micro pixel processing technology along with features such as light weight, thinness and low power consumption, and its application range is gradually widened. The trend is losing. The liquid crystal display device includes a liquid crystal panel, a driving circuit unit for driving the liquid crystal panel, a backlight unit for supplying a light beam to the liquid crystal panel, and a polarizing plate.

이하, 종래의 액정표시장치의 편광판 보호필름의 각 구성부와 이들 구성부가 갖는 단점을 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, each component of the polarizing plate protective film of the conventional liquid crystal display device and the disadvantages of these components will be described in detail with reference to the drawings.

도 1은 종래기술에 의한 액정표시장치의 구조를 도시한 사시도이며, 도 2는 종래기술에 의한 액정표시장치의 편광판 보호필름이 부착된 상태를 도시한 도면이다.1 is a perspective view illustrating a structure of a liquid crystal display device according to the prior art, and FIG. 2 is a view illustrating a state in which a polarizing plate protective film is attached to the liquid crystal display device according to the prior art.

도 1에 도시된 바와 같이 종래의 액정표시장치는, 하부 유리기판과 상부 유리기판의 사이에 매트릭스 형태로 배열된 액정셀로 구성되는 액정패널(10)과, 상기 액정패널(10) 일면에 장착되는 백라이트유닛(20)과, 상기 상,하부 유리기판의 상,하부에 위치하여 상기 백라이트유닛(20)의 광빔의 편광특성을 변환시키는 편광판(30)의 조립으로 구성된다.As shown in FIG. 1, a conventional liquid crystal display device includes a liquid crystal panel 10 including liquid crystal cells arranged in a matrix between a lower glass substrate and an upper glass substrate, and mounted on one surface of the liquid crystal panel 10. The backlight unit 20 and the upper and lower glass substrates are positioned at the upper and lower parts of the polarizing plate 30 to convert the polarization characteristics of the light beam of the backlight unit 20.

전술한 액정패널(10)의 상,하부에 부착되는 편광판(30)에는 스크레치 및 파손으로부터 보호하기 위한 편광판 보호필름(40)이 편광판(30)의 상,하부면 각각에 부착되어 있다. 이때, 액정패널(10)과 마주보는 편광판(30)의 면에는 접착층이 존 재하여 액정패널(10)에 부착된다.In the polarizing plate 30 attached to the upper and lower parts of the liquid crystal panel 10 described above, a polarizing plate protective film 40 for protecting from scratches and damage is attached to each of the upper and lower surfaces of the polarizing plate 30. In this case, an adhesive layer is present on the surface of the polarizing plate 30 facing the liquid crystal panel 10 and attached to the liquid crystal panel 10.

편광판(30)을 액정패널(10) 상,하부면에 부착하기 위해서는 편광판(30) 접착층이 존재하는 면의 편광판 보호필름(40)을 먼저 제거한 후 액정패널(10) 상,하부면에 부착하여야 한다.In order to attach the polarizing plate 30 to the upper and lower surfaces of the liquid crystal panel 10, the polarizing plate protective film 40 on the surface where the polarizing plate 30 adhesive layer exists is first removed and then attached to the upper and lower surfaces of the liquid crystal panel 10. do.

그러나, 도 2에 도시된 바와 같이 종래의 편광판 보호필름(40)은 탈착이 용이하게 일단은 접착부(41)가 형성되어 편광판 보호필름(40)과 결합되고, 타단은 편광판 보호필름 외측으로 노출되는 탈착테입(42)을 편광판 보호필름(40)에 부착하여 형성되는데, 이는 편광판(30)과 편광판 보호필림(40) 사이의 접착력이 탈착테입(42)의 접착부(41)보다 접착력이 좋은 경우 편광판 보호필름(40)의 제거에 어려움이 따르는 문제점이 있게 된다. 즉 탈착테입(42) 일단에 형성된 접착부(41)와 편광판 보호필름(40) 간의 접착력이 편광판 보호필름(40)과 편광판(30) 사이의 접착력 보다 월등히 크지 않을 경우 탈착테입(42)을 이용하여 편광판 보호필름을 제거하기 어려우며, 이는 편광판 보호필름(40)의 표면상태에서도 크게 좌우된다.However, as shown in FIG. 2, the conventional polarizing plate protective film 40 is easily detachable and has one end of an adhesive portion 41 formed therein, which is combined with the polarizing plate protective film 40, and the other end is exposed to the outside of the polarizing plate protective film. The detachable tape 42 is formed by attaching the polarizing plate protective film 40 to the polarizing plate when the adhesive force between the polarizing plate 30 and the polarizing plate protective film 40 is better than the adhesive part 41 of the detachable tape 42. There is a problem that is difficult to remove the protective film 40. That is, when the adhesive force between the adhesive part 41 formed on one end of the detachable tape 42 and the polarizing plate protective film 40 is not significantly greater than the adhesive force between the polarizing plate protective film 40 and the polarizing plate 30, the detachable tape 42 is used. It is difficult to remove the polarizing plate protective film, which greatly depends on the surface state of the polarizing plate protective film 40.

또한, 탈착테입(42)은 작업자의 손으로 직접 부착하는 작업이므로 부착위치가 정확하지 않을 수 있으며, 이에 따른 기포 발생 및 이물질이 유입되는 문제점이 있게 된다.In addition, the detachable tape 42 may be attached directly by the operator's hand, so the attachment position may not be accurate, resulting in bubble generation and foreign matters.

따라서, 본 발명은 종래의 편광판 보호필름의 탈착 방법의 단점을 극복하는 액정표시장치의 편광판 보호필름을 제공하는 것을 목적으로 한다.Accordingly, an object of the present invention is to provide a polarizing plate protective film of a liquid crystal display device that overcomes the disadvantages of the conventional detachment method of a polarizing plate protective film.

본 발명은 편광판이 포함되는 액정표시장치에 있어서, 상기 편광판의 표면상에 위치되어 상기 편광판과 점착되며, 일단으로 탈착부가 형성되는 편광판 보호필름을 제공한다.The present invention provides a polarizing plate protective film in a liquid crystal display device including a polarizing plate, which is disposed on the surface of the polarizing plate and adhered to the polarizing plate, and has a detachable portion formed at one end thereof.
