1. A display apparatus, comprising:
a first substrate;
a first electrode, disposed on the first substrate;
a second substrate, disposed opposite to the first substrate;
a first microlens layer, disposed on the second substrate, having a plurality of first microlenses;
a second microlens layer, disposed on the first microlens layer, having a plurality of second microlenses;
a second electrode, disposed on the second microlens layer;
a blocking wall structure, at least disposed between the first electrode and the second electrode, having an accommodating space corresponding to the first electrode;
an electrophoresis medium, disposed in the accommodating space, wherein the first microlens layer and the second microlens layer are disposed between the second substrate and at least one portion of the electrophoresis medium; and
a plurality of particles, mixed within the electrophoresis medium;
wherein one of the first microlenses has a first convex surface protruding toward the at least one portion of the electrophoresis medium, one of the second microlenses has a second convex surface protruding toward the at least one portion of the electrophoresis medium, and the first convex surface is located between the second substrate and the second convex surface.
