1. A display panel comprising:
a first substrate comprising:
a first base substrate which comprises a display area comprising a plurality of pixel areas for image display and a non-display area around the display area, and
an align key pattern comprising an opaque material in a part of the non-display area;
a second substrate comprising:
a second base substrate overlapping the first base substrate and comprising a transparent material,
a light blocking structure on the second base substrate and in the non-display area, and
a hole overlapping the align key pattern and penetrating the light blocking structure;
a filling pattern configured to fill the hole;
a filling layer corresponding to at least the display area and filling a gap between the first substrate and the second substrate; and
