array circuit board of Liquid Crystal Display Device

PURPOSE: An array substrate for an LCD(Liquid Crystal Display) is provided to form a dummy pixel at the outline portion's non-display region of the array substrate so that the dummy pixel is always driven into black, thereby preventing the backlight phenomenon generated from a subpixel within a...

Zusammenfassung:	PURPOSE: An array substrate for an LCD(Liquid Crystal Display) is provided to form a dummy pixel at the outline portion's non-display region of the array substrate so that the dummy pixel is always driven into black, thereby preventing the backlight phenomenon generated from a subpixel within a display region adjacent to the non-display region. CONSTITUTION: A subpixel(P) arranged as a matrix shape within a display region(20) is partially overlapped with a TFT(Thin Film Transistor), a pixel electrode(17) and a gate line on which the pixel electrode(17) is positioned, thereby forming a storage capacitor(16). Dummy pixels formed at the non-display region(21) are formed at the positions adjacent to the last outside plural subpixels(P). The dummy subpixel(50) is electrically connected to the pixel electrode(17) within the dummy pixel(50) and a gate line(13') positioned on an upper portion of the pixel electrode(17). 본 발명에 의한 액정표시장치용 어레이 기판은, 다수의 서브픽셀이 매트릭스 형태로 구성되며 상기 서브픽셀을 통해 빛이 선택적으로 투과되는 표시영역과, 상기 표시영역의 외곽부에 형성되어 빛이 불투과되는 비표시영역으로 나뉘어지는 액정표시장치용 어레이 기판에 있어서, 상기 비표시영역에 항상 빛을 투과하지 못하도록 구동되는 다수의 더미 서브픽셀이 형성되어 있음을 특징으로 한다. 이와 같은 본 발명에 의하면, 어레이 외곽부와 인접한 표시영역 내의 서브픽셀에서 발생되는 빛샘 현상을 방지함으로써 액정표시장치 제조에 있어 불량 감소 및 제조 수율을 향상시키는 장점이 있다.
