Display module, flexible wire board and flexible wire board connecting method
First Claim
1. A display module which includes a display panel provided with external connection terminals and a flexible wire board having a wire pattern on a base material, terminals of the wire pattern of the flexible wire board and the external connection terminals of the display panel being bonded using an anisotropic conductive adhesive, the flexible wire board having an insulating protective layer for protecting the wire pattern, wherein:
- the insulating protective layer of the flexible wire board is extended inside the display panel while having the flexible wire board connected to the display panel.

Abstract
A display module, in which panel electrode terminals of a display panel are bonded to pattern terminals of a Cu foil pattern of a flexible wire board by using an anisotropic conductive adhesive, has a solder resist for protecting the Cu foil pattern on a base material of the flexible wire board so that the solder resist is extended inside the display panel while having the flexible wire board connected to the display panel. Therefore, even when the flexible wire board is used in a bent state, poor connection is surely prevented while conveniently suppressing a break in wire of the Cu foil pattern when bent, thereby attaining a highly reliable display module.
