Abstract
A display apparatus includes a light-transmitting structural plate, some optical microscopic structures, an optical film, a base plate and some light emitting elements. The light-transmitting structural plate has a first side and a second side opposite to each other. The optical microscopic structures are regularly arrayed and formed on the first side or the second side. The optical microscopic structure has an inclined surface connecting at a connecting line and forming an angle ranging between 30 degrees and 150 degrees with a corresponding inclined surface of an adjacent one of the optical microscopic structures. The optical film is located on the first side. The base plate is separated from the second side by a space. The light emitting elements are located inside the space and disposed on the base plate. The light emitting elements respectively emit a light ray to the light-transmitting structural plate.
