A high-speed flat panel display has thin film transistors in a pixel array portion in which a plurality of pixels are arranged and a driving circuit portion for driving the pixels of the pixel array portion, which have different resistance values than each other or have different geometric structures than each other. The flat panel display comprises a pixel array portion where a plurality of pixels are arranged, and a driving circuit portion for driving the pixels of the pixel array portion. The thin film transistors in the pixel array portion and the driving circuit portion have different resistance values in their gate regions or drain regions than each other, or have different geometric structures than each other. One thin film transistor has a zigzag shape in its gate region or drain region or has an offset region.

A pattern film in accordance with one aspect of the present invention includes a first film and a second film. A first pattern array is built in the first film. The second film is attached to the first film. Further, a second pattern array is built in the second film. The second pattern array is partially overlapped with the first pattern array. The first and the second pattern arrays may be electrically connected to each other by a pressurizing process. Thus, a time and a cost for manufacturing the pattern film may be reduced. As a result, a printed circuit board and a semiconductor package having the pattern film may also be manufactured at a low expense.

A display device that requires less manufacturing time is presented. The display device includes a light blocking member formed on a substrate, a semiconductor layer formed on the light blocking member, and a gate insulating layer formed on the semiconductor layer. Gate conductors, a first interlayer insulating layer, data conductors, a second interlayer insulating layer, and a pixel electrode are formed. A third interlayer insulating layer is deposited with an opening that extends to the pixel electrode. An organic light emitting member is formed in the opening, and a common electrode is formed. The light blocking member contains nickel and silicon oxide. The presence of nickel-and-silicon-oxide light blocking member below the semiconductor improves the crystallizing speed for the semiconductor layer, reducing the overall manufacturing time. Further, the light blocking member is disposed under the pixel electrodes to prevent light leakage, improving the contrast ratio and image quality.
