Field of the Invention The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display module that can simplify and at the same time strengthen the ground of a printed circuit board.

정보화 사회가 발전함에 따라 표시장치에 대한 요구도 다양한 형태로 점증하 고 있으며, 이에 부응하여 근래에는 LCD(Liquid Crystal Display), PDP(Plasma Display Panel), ELD(Electro Luminescent Display), VFD(Vacuum Fluorescent Display) 등 여러 가지 평판 표시 장치가 연구되어 왔고, 일부는 이미 여러 장비에서 표시장치로 활용되고 있다. As the information society develops, the demand for display devices is increasing in various forms, and in recent years, liquid crystal display (LCD), plasma display panel (PDP), electro luminescent display (ELD), and vacuum fluorescent (VFD) have been developed. Various flat panel display devices such as displays have been studied, and some of them are already used as display devices in various devices.

그 중에, 현재 화질이 우수하고 경량, 박형, 저소비 전력의 장점으로 인하여 이동형 화상 표시장치의 용도로 CRT(Cathode Ray Tube)를 대체하면서 LCD가 가장 많이 사용되고 있으며, 노트북 컴퓨터의 모니터와 같은 이동형의 용도 이외에도 방송신호를 수신하여 디스플레이하는 텔레비전, 및 컴퓨터의 모니터 등으로 다양하게 개발되고 있다.Among them, LCD is the most widely used as a substitute for CRT (Cathode Ray Tube) for the use of mobile image display device because of the excellent image quality, light weight, thinness, and low power consumption, and mobile type such as monitor of notebook computer. In addition, it is being developed in various ways, such as a television for receiving and displaying broadcast signals, and a monitor of a computer.

이와 같이 액정표시장치가 여러 분야에서 화면 표시장치로서의 역할을 하기 위해 여러 가지 기술적인 발전이 이루어졌음에도 불구하고 화면 표시장치로서 화상의 품질을 높이는 작업은 상기 장점과 배치되는 면이 많이 있다.As described above, although various technical advances have been made in order for the liquid crystal display device to serve as a screen display device in various fields, the task of improving the image quality as the screen display device has many advantages and disadvantages.
