Abstract (en)

[origin: WO2008040306A1] An optical waveguide (1) with a main extension direction, at least one radiation entry surface (2) and a radiation exit surface (3), which extends along the main extension direction, is described, wherein at least one radiation exit surface (2) extends transversely to the main extension direction (3), and the at least one radiation entry surface (2) has two convexly curved partial regions (4a, 4b) which are connected to one another by a kink-type or concavely shaved indentation (5). Furthermore, an optical apparatus designed with such an optical waveguide and a display apparatus are described.
