Abstract
A picking apparatus is configured to pick up a plurality of micro elements. The picking apparatus includes a main body and a plurality of picking portions. The picking portions connect with and protrude from the main body. Each of the picking portions has a first surface. The first surfaces are away from the main body and configured to pick up the micro elements. The main body has a second surface at least partially located between the picking portions. Each of the first surfaces has a first viscosity. The second surface has a second viscosity. The second viscosity is less than the first viscosity.
