A flat panel display device and method of manufacturing the display device. The display device comprises a first substrate and a connection pad located along a side of the first substrate. A second substrate overlaps with the first substrate, wherein the second substrate does not overlap with an exposed portion of the first substrate. A first contact pad electrically couples the second substrate and the first substrate. A first distance from the side of the first substrate to a boundary between the exposed portion of the first substrate and the second substrate is greater than a second distance from the side of the first substrate to the first contact pad. The display device may be, for example, a touch capable display device that uses the first contact pad to transfer touch sensing signals from the second substrate to the first substrate.

The present invention relates to a pyrene-containing conductive polymer represented by formula 1 and an organic solar cell comprising the same as an organic photovoltaic material. The conductive polymer has improved hole mobility as a result of introducing a specific amount of pyrene either into a polymer, which consists only of a donor functional group comprising one or more aromatic monomers, or into a donor-acceptor type polymer comprising a repeating acceptor introduced into a donor functional group. Thus, the conductive polymer can be used as an organic photovoltaic material in organic photodiodes (OPDs), organic light-emitting diodes (OLEDs), organic thin-film transistors (OTFTs), organic solar cells and the like. In addition, an organic solar cell showing high power conversion efficiency (PCE) can be provided using an organic photovoltaic material comprising the pyrene-containing conductive polymer as an electron donor.
