Abstract: A display apparatus includes: an output unit to form an image and output it to the front; a lens unit disposed in front of the output unit to transmit the image to be output and transfer the image to the front; a guide unit formed to be long and having at least one pair of total reflection surfaces, a part of which is disposed between the output unit and the lens unit, in which a transmission path through which the illumination light is incident to move to the other side through at least one or more internal total reflections is formed; and a diffraction unit which is disposed on the transmission path and transmits the illumination light incident with a predetermined pattern to the output unit at a predetermined angle.

Abstract: Disclosed is an omnidirectional camera module comprising a dome-shaped cover unit, including: a body including a barrel portion in which a plurality of lenses are disposed in series and through which light introduced from one side travels and an extended portion formed to have a relatively large area on one side of the barrel portion and to communicate with the barrel portion at a central portion; a cover unit having a shape convex to the front, having at least a portion made of a light transmitting material, surrounding the extended portion at the front, and forming a reflection space therein; and a reflection unit including a first reflective portion formed on a front surface of the extended portion inside the reflection space, and a second reflective portion disposed to face the first reflective portion inside the cover unit to reflect the light reflected by the first reflective portion again.
