Abstract

Provided is a circuit board wherein the connection strength of conductive materials, such as an anisotropic conductive film, is improved. A first region (12) wherein a predetermined number of electrode terminals (121) are provided, and a second region (13) wherein a predetermined number of island-like structures (131a) are provided are arranged in the first direction. At least some of the island-like structures (131a) have the dimension in the direction substantially perpendicular to the first direction set smaller than the dimension of the second region (13) in the direction substantially perpendicular to the first direction.

Description

technical field [0001] The present invention relates to a circuit board, a connection structure of the circuit board, and a display panel assembly, and particularly relates to a circuit board capable of being connected to other circuit boards using conductive materials such as anisotropic conductive films; A circuit board connection structure in which circuit boards and the like are connected to each other by a permanent material; and a display panel assembly having the circuit board. In addition, the term "display panel assembly" refers to a member in which a predetermined circuit board is connected to a display panel. Background technique [0002] A general active matrix liquid crystal display panel includes a TFT array substrate and an opposing substrate (a color filter is generally applied to the opposing substrate). In addition, the TFT array substrate and the counter substrate are attached to each other at a predetermined minute interval, and liquid crystals are fille...
