Display device

A display device, comprising:

• a first substrate;
• a first alignment layer, disposed on the first substrate;
• a second substrate, disposed opposite to the first substrate;
• a plurality of first protrusions, disposed on the second substrate and separated from each other;
• a second alignment layer, disposed on the second substrate and the first protrusions, wherein the first alignment layer and the second alignment layer are located between the first substrate and the second substrate;
• and
• a display medium, located between the first alignment layer and the second alignment layer,
• wherein a surface of the first alignment layer and a surface of the second alignment layer facing the display medium have topographies with a plurality of different irregular areas surrounded by a plurality of micro-structures, the micro-structures substantially form a wall by jointing with each other, each of the topographies with the different irregular areas is surrounded by the wall, the micro-structures comprise a plurality of first micro-structures, and the first micro-structures are disposed on the first protrusions.
