Curved display panel

A curved display panel comprising a bending axis parallel to a first direction, comprising:

• a first substrate;
• a second substrate;
• a plurality of sub-pixels disposed on the first substrate, wherein each of the sub-pixels includes a longer edge and a shorter edge, the shorter edge is parallel to the first direction, the longer edge is parallel to a second direction, and the first direction and the second direction are not parallel;
• a plurality of first metal lines disposed on a surface of the first substrate and extending in the first direction, wherein each of the sub-pixels is disposed corresponding to one of the first metal lines;
• and
• a first black matrix layer disposed between the first substrate and the second substrate, wherein the first black matrix layer comprises a plurality of first black matrix patterns extending in the first direction, and one of the first black matrix patterns overlaps two adjoining first metal lines in the normal direction.
