Abstract
Abstract A display device includes a display panel having electrodes with a plurality of terminals, a driver circuit having electrodes corresponding to the display panel electrodes, and an anisotropic conductive film for electrically connecting the display panel electrodes with the driver circuit electrodes. The connecting part of each of the driver circuit electrodes to be connected with each of the display panel electrodes includes a first connecting portion and a second connecting portion, where the first connecting portion is more narrow than the second connecting portion.
