摘要： A mask includes a transparent substrate, a light-blocking layer and a halftone layer. The light-blocking layer includes a source electrode pattern portion including a first electrode portion, a second electrode portion and a third electrode portion, and a drain electrode pattern portion disposed between the second electrode portion and the third electrode portion. The halftone layer includes a halftone portion corresponding to a spaced-apart portion between the source electrode pattern portion and the drain electrode pattern portion, and a dummy halftone portion more protrusive than ends of the second electrode portion and the third electrode portion. Thus, a photoresist pattern corresponding to a channel portion of a thin film transistor (TFT) may be formed with a uniform thickness, to thereby prevent an excessive etching of the channel portion.

摘要： An output part outputs a high voltage of a first clock signal as a high voltage of an (m)-th gate signal (‘m’ is a natural number) and a low voltage in response to a high signal of an (m+1)-th gate signal outputted from an (m+1)-th stage. A first maintenance part maintains a control part of the pull-up part at a low voltage in response to an (m−1)-th node signal or an (m+1)-th node signal lower than a high signal of a second clock signal having a phase opposite to the phase of the first clock signal received from an (m−1)-th stage or the (m+1)-th stage. A second maintenance part maintains the low voltage of the (m)-th gate signal in response to the (m−1)-th node signal or the (m+1)-th node signal.
