| description | The present invention provides a flexible circuit board for a display, the flexible circuit board having a chip-on-film structure in which a connection pattern selected as a first connection pattern from among connection patterns connected with a panel contact pad is confined inside a product portion and is not in contact with a dicing line, and a second connection pattern selected as a second connection pattern from among the connection patterns connected with the panel contact pad is not in contact with the dicing line. Thus, the connection pattern selected as the first connection pattern is prevented from being exposed to a cut cross-section of the cut line, and electrical characteristics of the connection pattern selected as the first connection pattern are prevented from changing due to permeation of moisture.
本发明提供了一种用于显示器的柔性电路板，该柔性电路板具有膜上芯片结构，其中，从与面板接触焊盘连接的连接图案中选择为第一连接图案的连接图案被限制在产品部分的内部，并且不与切割线接触，从而防止被选择为第一连接图案的连接图案暴露于切割线的切割剖面，并且防止被选择为第一连接图案的连接图案的电特性因水分的渗透而改变。 |
