Display devices and methods for forming display devices

A display device, comprising:

• a thin-film transistor substrate;
• a conductive pad disposed on the thin-film transistor substrate;
• an adhesion film disposed on the conductive pad, the adhesion film comprising a plurality of conductive particles;
• a light-emitting component disposed on the adhesion film, the light-emitting component comprising a first connection feature and a second connection feature;
• and
• a protection layer partially surrounding the light-emitting component, wherein each of the first connection feature and the second connection feature has a lower portion not surrounded by the protection layer and the protection layer between the first connection feature and the second connection feature comprises an organic sub-layer and an inorganic sub-layer, and
• wherein the adhesion film has a thickness of T, one of the plurality of conductive particles has a diameter of d, the lower portion of the connection feature has a thickness of t, and 0<t≤T−d.
