Abstract

A pixel unit includes a substrate, a wiring layer and three light-emitting elements. The wiring layer includes first electrode wires and second electrode wires. The first electrode wires and the second electrode wires are arranged side by side and separated from each other by a spacing. A first blocking wall structure is at a first end portion of each of the first electrode wires, the first end portion is near the corresponding second electrode wires, and a second blocking wall structure is at a second end portion of each of the second electrode wires, the second end portion is near the corresponding first electrode wires. Three light-emitting elements emit red light, green light and blue light respectively. The light-emitting elements are in a flip chip configuration and are connected to one of the first electrode wires and one of the second electrode wires adjacent to each other respectively.
