Display apparatus

A display apparatus, comprising:

• a reflective display panel, having a display surface;
• a light guide plate, disposed on one side of the display surface of the reflective display panel, and having a first light incident surface and a first surface connected to each other, the first surface faces the display surface of the reflective display panel;
• a first light source, disposed on one side of the first light incident surface of the light guide plate, and configured to emit a plurality of first light beams toward the first light incident surface of the light guide plate;
• and
• a plurality of optical microstructures, disposed on a second surface of the light guide plate. wherein the second surface connects the first light incident surface and is opposite to the first surface, the plurality of optical microstructures each have a plane, the plane is parallel to the second surface, and an included angle between an extension direction of each of the plurality of optical microstructures and the first light incident surface of the light guide plate is greater than or equal to 45 degrees and less than or equal to 90 degrees, wherein the included angle between the extension direction of each of the plurality of optical microstructures and the first light incident surface of the light guide plate is less than 90 degrees.
