Abstract
A display device includes, among other things, a pad area having a pattern that may reduce the distance gap between the signal lines cause by the contour changes of the signal lines. A corresponding print circuit board may also include a similar pattern to assimilate the distance gap between the lead wires. The pad and print circuit board may contact through anisotropic conductive film.
Claims13
A display device, comprising:
- a base substrate having a display area and a non-display area including a pad area;
- a plurality of signal wires disposed on the base substrate extending in a first direction from an end portion of the base substrate and spaced apart from one another in a second direction which intersects the first direction, said signal wires having upper surfaces;
- a pattern disposed among the plurality of signal wires on an outermost portion of the base substrate without overlapping the upper surfaces of the signal wires;
- a printed circuit board attached on the pad area and comprising a driving integrated circuit, and a plurality of lead wires connected to the driving integrated circuit and spaced apart from one another in the second direction,
- wherein each of the plurality of lead wires includes:
- a first lead portion which has a first width,
- a second lead portion which has a second width that is narrower than the first width and is disposed between the first lead portion and the driving integrated circuit, and
- a third lead portion which is disposed between the first lead portion and the second lead portion, wherein the third lead portion has a third width that gradually increases from the second lead portion to the first lead portion.
