Claim:
1. A display panel, comprising: a first substrate with a plurality of pixel units disposed thereon, wherein the pixel units respectively comprise a plurality of sub-pixel units, and the sub-pixel units comprise a first sub-pixel unit being red color, a second sub-pixel unit being blue color, and a third sub-pixel unit being green color; a second substrate opposite to the first substrate; a liquid crystal layer disposed between the first substrate and the second substrate; and plural metal pads disposed on the first substrate, respectively having a first protrusion portion, and respectively corresponding to the sub-pixel units; wherein when light passes through the sub-pixel units, dark line patterns are exhibited, which respectively comprise: a first main dark line extending along a first direction, wherein two opposite edges of the first main dark line respectively have a first dark-line edge point and a second dark-line edge point at a cross-sectional line along a second direction perpendicular to the first direction; and a metal pad pattern corresponding to the first main dark line and having a first protrusion pattern extending along the first direction, wherein the first protrusion pattern corresponds to the first protrusion portion of the metal pad, two opposite edges of the first protrusion pattern respectively have a first metal-pad-pattern edge point and a second metal-pad-pattern edge point at another cross-sectional line along the second direction, the first metal-pad-pattern edge point is relatively close to the first dark-line edge point, and the second metal-pad-pattern edge point is relatively close to the second dark-line edge point, wherein a distance between elongation lines along the first direction on the basis of the first metal-pad-pattern edge point and the first dark-line edge point is defined as a first deviation distance, a distance between elongation lines along the first direction on the basis of the second metal-pad-pattern edge point and the second dark-line edge point is defined as a second deviation distance, and the first deviation distance is different from the second deviation distance, wherein one of the first deviation distance or the second deviation distance in the first sub-pixel unit is larger than one of the first deviation distance or the second deviation distance in the third sub-pixel unit.
