OLED display device that prevents shorting of interconnections during manufacture thereof

An organic light emitting diode (OLED) display device, comprising:

• first and second substrates facing each other;
• a gate insulating layer, a gate electrode, an interlayer insulating layer, a first source/drain electrode, a second source/drain electrode, a protection layer, a planarization layer, a first pixel electrode and a second pixel electrode arranged on the first substrate;
• an emission region arranged between the first substrate and the second substrate, the emission region including a plurality of signal lines;
• a sealant arranged along an edge of the emission region to adhere the first and second substrates together;
• a non-emission region arranged outside the sealant;
• a plurality of interconnections extending from the signal lines in the emission region through the sealant and into the non-emission region;
• and
• a plurality of cladding parts covering at least a portion of each of the plurality of interconnections at a location corresponding to where the interconnections extend through the sealant, the cladding parts including a material having a higher melting point than that of the interconnections, wherein each of said cladding parts covers sides and a portion of a top surface that is less than an entirety of the top surface of a corresponding one of said interconnections at a location corresponding to where the one of said interconnections extends through the sealant, wherein the plurality of cladding parts are comprised of substantially a same composition as that of the first pixel electrode.
