LIQUID CRYSTAL DISPLAY ELEMENT

摘要

PROBLEM TO BE SOLVED: To effectively prevent the disconnection of an output electrode of a flexible board due to bending, reduction of inter-lead insulation due to deviation of positions in a connection step and also the disconnection of a lead electrode on the side of a liquid crystal panel due to a flaw or the like in a liquid crystal display element wherein the flexible board is connected to the liquid crystal panel. SOLUTION: A first connection surface 110 having an equilateral trapezoidal shape whose tip (an upper side) 101 has a width narrower than that of a lower side 102 is formed at the panel side lead electrode 100 and a second connection surface 210 having an equilateral trapezoidal shape whose tip (an upper side)201 has a width narrower than that of a lower side 202 is formed at a board side output electrode 200. The first and the second connection surfaces 110 and 210 are connected via an adhesive means containing conductive particles in the state that the connection surfaces are vertically reversed to each other.
