Light-emitting diode display

A light-emitting diode display having a plurality of sub-pixel regions, each of the sub-pixel regions comprising:

• a substrate having an active device;
• a first electrode and a second electrode separately disposed on the substrate, wherein the first electrode is electrically connected to the active device, and a horizontal distance between the first electrode and the second electrode is W1;
• a light-emitting diode disposed on the substrate, and comprising a semiconductor stack, a first pad, and a second pad, wherein the first pad and the second pad are separately disposed on the semiconductor stack, the first pad contacts the first electrode, the second pad contacts the second electrode, and a maximum thickness of the semiconductor stack is H1;
• and
• at least one blocking wall disposed on the substrate, and located between the first pad and the second pad to prevent a contact between the first pad and the second pad, wherein a height of the at least one blocking wall is H2 and a width of the at least one blocking wall is W2,
• wherein H2≤½H1, and W2≤W1.
