Abstract:
A display device, comprising:a glass substrate having a display area where a plurality of pixels are arranged and peripheral area where a plurality of driver circuits each supplying signals to a corresponding group of the plurality of pixels are juxtaposed along an edge of the glass substrate and a plurality of groups of input terminals each arranged between the driver circuits; and a flexible printed circuit board which has a plurality of groups of connection terminals each corresponding to one of the plurality of groups of input terminals, the respective connection terminals belonging to each of the groups electrically connected to the respective input terminals belonging to a corresponding one of the plurality of groups of input terminals, wherein the flexible printed circuit board is formed of a pair of flexible films and first conductive layers interposed between the pair of flexible films, and includes a trunk portion being extended along the edge of the glass substrate and a plurality of branch portions each being protruded from the trunk portion to the edge of the glass substrate, each of the plurality of branch portions corresponds to one of the plurality of groups of connection terminals and has each of the connection terminals belonging to the one of the plurality of groups of connection terminals formed on an outer surface of one of the pair of flexible films thereof, each of the plurality of groups of connection terminals is connected to the corresponding one of the plurality of groups of input terminals with an anisotropic conductive film, each of the first conductive layers is extended from the trunk portion to one of the plurality of branch portions to oppose to one of the plurality of groups of connection terminals, and second conductive layers are interposed between the pair of flexible films in the trunk portion and each of the second conductive layers is disposed between an adjacent pair of the first conductive layers to be spaced from one another.
