Abstract: An organic light emitting diode (OLED) display device having a pixel area and a pad area. The pad area includes a silicon layer pattern arranged on the substrate, an insulating layer arranged on the silicon layer pattern, an interconnection layer arranged on the insulating layer, and a protective layer surrounding an edge of the interconnection layer and having an opening exposing the interconnection layer. Since a surface area of the interconnection layer is increased due to a roughness of the underlying polycrystalline silicon layer pattern in the pad area, resulting in increased contact area and reduced contact resistance between parts configured to operate a flat panel display device and the interconnection layer is increased.

Abstract: A thin film transistor (TFT) array arrangement, an organic light emitting display device that includes the TFT array arrangement and a method of making the TFT array arrangement and the organic light emitting display device. The method seeks to reduce the number of masks used in the making of the TFT array arrangement by employing half-tone masks that are followed by a two step etching process and by forming layers of the capacitor simultaneous with the formation of layers of the source, drain and pixel electrodes. As a result, individual layers of the capacitor are on the same level and are made of the same material as ones of the layers of the source, drain and pixel electrodes. The capacitor has three electrodes spaced apart by two separate dielectric layers to result in an increased capacity capacitor without increasing the size of the capacitor.

Sum of the second length of the second light blocking unit and the third length of the semi-transmitting unit is larger than the first length of the first blocking unit.
