Light-emitting device, manufacturing method thereof and display module using the same

A light-emitting device, comprising:

• a carrier, comprising a first top surface, and a first electrically conductive region disposed on the first top surface and comprising a lateral surface;
• a light-emitting element, including a lateral boundary, a bottom surface, a second top surface and a first contact electrode formed directly under the bottom surface without extending beyond the lateral boundary, wherein the first contact electrode faces to the first electrically conductive region;
• and
• a connection structure, including a first electrical connection portion electrically connecting the first electrically conductive region and the first contact electrode, and a protective portion connected to the bottom surface and fully surrounding the first contact electrode and the first electrical connection portion without fully covering the second top surface,
• wherein the first electrical connection portion is cured and includes an upper portion, a lower portion, and a neck portion located between the upper portion and the lower portion,
• wherein the first electrical connection portion directly contacts at least part of the lateral surface, and
• wherein the neck portion has a width which is smaller than that of the upper portion and the lower portion.
