Patent ID: 7923176

Claim:
A mask comprising: a transparent substrate; a light-blocking layer formed on the transparent substrate, the light-blocking layer comprising: a source electrode pattern portion comprising a first electrode portion extending in a first direction, a second electrode portion bent from a first end of the first electrode portion and extending in a second direction substantially perpendicular to the first direction and a third electrode portion bent from a second end of the first electrode portion and extending in the second direction; and a drain electrode pattern portion disposed between the second electrode portion and the third electrode portion and extending in the second direction, the drain electrode pattern portion and the source electrode pattern portion disposed in non-overlapping positions so as to form a spaced-apart portion between the drain pattern portion and the source electrode pattern portion; and a halftone layer formed on the transparent substrate, the halftone layer comprising: a halftone portion corresponding to the spaced-apart portion between the source electrode pattern portion and the drain electrode pattern portion; and a dummy halftone portion connected to the halftone portion and more protrusive than an end of the second electrode portion and an end of the third electrode portion in the second direction.
