Display device

A display device comprising:

• a resin layer;
• a film substrate bonded to one surface of the resin layer by using an adhesive layer;
• a display region provided on another surface of the resin layer opposite to the one surface of the resin layer;
• and
• a frame region provided around the display region,
• wherein, in the frame region, a plurality of external signal input wiring lines, a driving chip including a plurality of input terminals and a plurality of output terminals, and a plurality of lead wiring lines extending from the display region are provided,
• each of the plurality of input terminals of the driving chip is disposed on a corresponding one of the plurality of external signal input wiring lines and is electrically connected to the corresponding one of the plurality of external signal input wiring lines by using an anisotropic conductive material,
• each of the plurality of output terminals of the driving chip is disposed on a corresponding one of the plurality of lead wiring lines and is electrically connected to the corresponding one of the plurality of lead wiring lines by using the anisotropic conductive material,
• in the film substrate, a first slit being formed by removing thickness of the film substrate is formed, and
• in the film substrate, the first slit is formed in at least a part of a region overlapping a region between the plurality of input terminals of the driving chip and the plurality of output terminals of the driving chip.
