Display device

A display device, comprising:

• a circuit substrate;
• a plurality of pad sets, disposed on the circuit substrate, and each pad set including:
• a first pad;
• and
• a second pad surrounding the first pad;
• and
• a plurality of light-emitting elements, disposed above the circuit substrate, and each light-emitting element including a first electrode, a second electrode and a light-emitting stack between the first electrode and the second electrode;
• wherein the first electrode is electrically connected to the first pad, the second electrode is electrically connected to the second pad, and an orthographic projection of the second electrode on the circuit substrate is overlapped with an orthographic projection of the first pad on the circuit substrate,
• wherein a vertical spacing between the second pad and the circuit substrate is greater than a vertical spacing between the first pad and the circuit substrate in a cross-sectional view cut through the first pad, the second pad and the circuit substrate;
• further comprising:
• a transparent conductive layer electrically connecting the second electrode to the second pad, wherein the first electrode is disposed between the first pad and a bottom surface of the light-emitting stack, the second electrode is disposed between a top surface of the light-emitting stack and the transparent conductive layer, the transparent conductive layer covers the top surface and a sidewall of the light-emitting stack without touching the bottom surface of the light-emitting stack, and the sidewall of the light-emitting stack connects the top surface of the light-emitting stack to the bottom surface of the light-emitting stack;
• and
• a planarization layer disposed between the second pads of the plurality of pad sets and the circuit substrate and having a plurality of openings, wherein the first pads of the plurality of pad sets are disposed in the plurality of openings respectively, and the second pads of the plurality of pad sets are disposed on the planarization layer.
