통상, 액정표시장치(Liquid Crystal Display; LCD)는 스위칭 소자인 박막트랜지스터(Thin Film Transistor : 이하 "TFT"라 함)를 이용하여 자연스러운 동화상을 표시하고 있다. 이러한 액정표시장치는 브라운관에 비하여 소형화가 가능하여 휴대용 텔레비젼이나 랩탑(Lap-Top)형 퍼스널 컴퓨터 등의 모니터로서 상품화되고 있다.In general, a liquid crystal display (LCD) displays a natural moving image by using a thin film transistor (hereinafter referred to as TFT) as a switching element. Such a liquid crystal display device can be miniaturized compared to a CRT and commercialized as a monitor such as a portable television or a laptop (Lap-Top) type personal computer.

액정표시장치는 게이트라인들과 데이터라인들의 교차부들 각각에 배열되어진 화소들이 비디오신호에 따라 광투과율을 조절함으로써 액정패널에 비디오신호에 해당하는 화상을 표시하게 된다. 화소들 각각은 데이터라인으로부터의 데이터신호의 전압레벨에 따라 투과 광량을 조절하는 액정셀을 포함한다. TFT는 게이트라인과 데이터라인들의 교차부에 설치되어 게이트라인으로부터의 스캔신호에 응답하여 액정셀쪽으로 전송될 데이터신호를 절환하게 된다.The liquid crystal display device displays pixels corresponding to the video signal on the liquid crystal panel by adjusting the light transmittance of the pixels arranged at the intersections of the gate lines and the data lines according to the video signal. Each of the pixels includes a liquid crystal cell that adjusts the amount of transmitted light according to the voltage level of the data signal from the data line. The TFT is provided at the intersection of the gate line and the data lines to switch the data signal to be transmitted to the liquid crystal cell in response to the scan signal from the gate line.

이와 같은 액정표시장치는 데이터라인들과 게이트라인들에 접속되어 각각의 데이터신호와 스캔신호를 데이터라인들과 게이트라인들에 공급하기 위한 다수의 구동집적회로들이 필요하게 된다. 다수의 구동집적회로들은 인쇄회로보드(Printed Circuit Board : 이하 "PCB"라 함)와 액정패널 사이에 설치되어 PCB로부터 공급되 는 제어신호에 응답하여 액정패널의 데이터라인들과 게이트라인들에 데이터신호와 스캔신호를 공급하게 된다.Such a liquid crystal display requires a plurality of driving integrated circuits connected to data lines and gate lines to supply respective data signals and scan signals to the data lines and gate lines.

In addition, various types of electronic components such as an AC-AC converter and a system interface (not shown) are mounted on the PCB 32.

PCB(32)의 일측에는 연결부(34)가 형성된다. 여기서, 연결부(34)는 테이프 캐리어 패키지(Tape Carrier Package : 이하 "TCP"라 함, 46)를 통해 영상을 표시하기 위한 액정패널(48)의 입력단에 접속되며, 이 연결부(34)는 PCB(32)로부터의 신호를 액정패널(48)에 공급한다.The connection part 34 is formed at one side of the PCB 32.

The ground pattern 60 removes electric shock flowing along the solder resistor 58, thereby reducing component stress and improving resistance to electric shock.
