LIQUID CRYSTAL DISPLAY CAPABLE OF CONTACTING A PORTION OF A LOWER PART OF A VIA HOLE WITH A GATE METAL COMMON ELECTRODE AND A FIRST LAYER TRANSPARENT COMMON ELECTRODE TO INCREASE DISPLAY QUALITY AND AN ARRAY SUBSTRATE THEREOF

摘要

PURPOSE: A liquid crystal display and an array substrate thereof are provided to transmit a voltage signal of a gate metal common electrode to a first layer transparent common electrode through a second layer transparent common electrode of a lower portion of a via hole, thereby normally displaying a pixel while common electrode signals of two adjacent pixel rows are normally and conductively connected each other.;CONSTITUTION: A gate metal common electrode(11) is formed on a first layer transparent common electrode(2). A via hole(14) is formed on an insulating layer. A second layer transparent common electrode(13) is formed on the insulating layer. A partial edge of the via hole contacts the gate metal common electrode. The partial edge of the via hole contacts the first layer transparent common electrode. The second layer transparent common electrode is electrically connected to the first layer transparent common electrode and the gate metal common electrode.;COPYRIGHT KIPO 2013
