Abstract: A display apparatus including a display device, a first prism and a second prism is provided. A part of a light beam from a display area of the display device that is covered by a first light entering surface of the first prism penetrates the first light entering surface and is sequentially refracted by a reflective refractive surface of the first prism to above the display area. Another part of the light beam from the display area that is covered by the first light entering surface penetrates the first light entering surface, is reflected by the reflective refractive surface, penetrates a first light exiting surface of the first prism, a gap, a second light entering surface of the second prism and a second light exiting surface of the second prism sequentially, and is transmitted to above a frame area of the display device.

Abstract: A display apparatus includes a display device and a prism module. The display device has a display area and a frame area surrounding the display area. The prism module is disposed above the frame area. The prism module includes a plurality of first prism sets and at least one second prism set. The first prism sets are respectively disposed beside a plurality of edges of the display area. The second prism set is disposed beside at least one corner of the display area, and the second prism set is adjacent to the first prism sets. The second prism set includes a plurality of prisms, and the prisms are arranged in a direction away from the corner of the display area. The extending direction of each of the prisms of the second prism set is inclined with respect to the edges of the display area which are adjacent to the corner.
